T7200/T7300 Relay Logic  
The T7200/T7300 contains three switching relays. In  
conventional applications, the relays control first stage  
cooling, first stage heating, and fan. In heat pump  
applications, the relays control the heat pump compressor,  
auxiliary heat, and the fan. Because of this change in  
switching logic, it is important to use a Q7300C,D,  
Q7300H2003, or Q7300H2011 Subbase when the T7300 is  
set for heat pump applications and a Q7300A,G,  
Q7300H2029 Subbase when the T7300 is set for  
conventional applications.

T7200D,E, T7300D,E,F AND Q7300 SERIES 2000 PROGRAMMABLE COMMERCIAL THERMOSTATS AND SUBBASES  
T7200/T7300 and Conventional Thermostats  
T7200/T7300 Thermostat Operation  
P+I Control  
Startup  
The T7200/T7300 microprocessor based control requires that  
the user understands temperature control and thermostat  
performance. A conventional electromechanical or electronic  
thermostat does not control temperature precisely at setpoint.  
Typically, there is an offset (droop) in the control point as the  
system load changes. This is a phenomenon that most people  
in the industry know and accept. Many factors contribute to  
offset including switch differential, thermal lag, overshoot,  
cycle rates and system load.  
When power to the thermostat is turned on, a startup and  
initialization program begins. The startup occurs only on initial  
powerup. After total loss of power for an extended period, the  
current time and day may need to be set, but the user  
program is held. The initial default values are heating 68°F  
(20°C) and cooling 78°F (26°C) for the Occupied periods.  
Unoccupied default values are heating 55°F (13°C) and  
cooling 90°F (32°C).  
NOTE: The thermostat controls to the Unoccupied default  
setpoints of 55°F (13°C) for heat and 90°F (32°C) for  
cool when no program is set.  
The thermostat microprocessor simultaneously gathers,  
compares and computes data. Using this data, it controls a  
wide variety of functions. The special proprietary algorithm  
(
program) in the thermostat eliminates the factors causing  
Occupied Operation  
offset. This makes temperature control more accurate than  
the conventional electromechanical or electronic thermostats.  
The temperature control algorithm is called proportional plus  
integral (P+I) control.  
When the thermostat is operating in the Occupied period,  
the temperature is controlled to the occupied heat or cool  
setpoint. The normally open (A1) auxiliary relay contacts are  
closed and the normally closed (A3) auxiliary relay contacts  
are opened during the Occupied periods (if the subbase being  
used has this option). The fan operates as follows: fan  
selection can be set to On (always energized) or Auto (cycles  
with Y1 or W1).  
The thermostat sensor, located on the thermostat or remote,  
senses the current space temperature. The proportional error  
is calculated by comparing the sensed temperature to the  
programmed setpoint. The deviation from the setpoint is the  
proportional error.  
Unoccupied Operation  
The thermostat also determines integral error, which is a  
deviation based on the length of error time. The sum of the  
two errors is the (P+I) error. The cycle rate used to reach and  
maintain the setpoint temperature is computed using the P+I.  
The addition of the integral error is what differentiates the  
thermostat from many other electronic and electromechanical  
thermostats. See Fig. 18.  
When the thermostat is operating in the Unoccupied period,  
the temperature is controlled to the Unoccupied heat or cool  
setpoint. The normally open (A1) relay contact is open and the  
normally closed (A3) relay contact is closed. The fan operates  
as follows: fan is always intermittent (cycles with Y1 or W1).  
Intelligent Recovery® Feature  
Intelligent Recovery is a Honeywell trademarked feature  
for the way the thermostat controls heating and cooling  
equipment during recovery from the Unoccupied to Occupied  
setting. During recovery, the control point changes gradually  
rather than shifting immediately from the energy saving  
setting to the comfort setting.

POINT  
When Intelligent Recovery is used in heating, the control point  
raises gradually, maximizing the use of the more economical  
first stage heat to bring the sensed temperature to the desired  
comfort setpoint. This minimizes using the typically more  
expensive second-stage heat.

versus P+I temperature control.  
Comfort and energy savings can be achieved in both  
heating and cooling.  
Heat cycling reduced, extending equipment life.  
Equipment Protection  
As part of the operational sequence, the T7200/T7300  
microprocessor also incorporates minimum on and off times  
for all heating and cooling stages. Minimum on time is set in  
the installer setup number 32. Using the minimum on and off  
times assures that rapid cycling of equipment does not occur,  
which extends equipment life. Minimum on and off times are  
set in the Installer Setup.  
RECOVERY FROM UNOCCUPIED  
The heat pump heat recovery ramp is 3°F (1.6°C) per hour.  
This differs from the 5°F (2.8°C) per hour for conventional  
systems. The 3°F helps the system use the economical heat  
pump more and the expensive auxiliary heat less. The cooling  
ramp is 5°F, the same as for conventional systems.

Conventional System  
The T7200 and T7300D,F Thermostats with Q7300A,G,H  
Subbases are designed for conventional heat/cool  
GENERAL OPERATION INFORMATION  
applications.  
Cycle Rates  
The thermostat control algorithm maintains the temperature  
by cycling stages of heating or cooling to meet setpoint.  
Heat Pump Operation  
The T7200E and T7300E,F Thermostats with Q7300C,D,H  
Subbases are designed for heat pump applications. Additional  
information is required when configured for heat pump  
applications.  
Subbase Auxiliary Relay  
The Q7300 Auxiliary Relay output acts as a time-of-day switch  
to be used with an economizer minimum position control. The  
normally open (A1) auxiliary relay contacts are closed during  
the Occupied period and open during the Unoccupied period.  
The normally closed (A3) auxiliary relay contacts are open  
during the Occupied period and closed during the Unoccupied  
period. The contacts are in the normal state during recovery.  
O AND B TERMINALS FOR HEATING OR COOLING CHANGEOVER  
The Q7300C controls heat pump changeover. The Q7300D,H  
is only used in a heat pump application when the heat pump  
controls the reversing valve changeover. See Table 12 for the  
operation of the O and B terminals on the Q7300C, H2003.  
O AND B TERMINALS ON A CONVENTIONAL SUBBASE  
Interfacing with Electromechanical  
Conventional subbase O and B terminals can be used to drive  
dampers and valves. The O terminal is energized on a call for  
cool and the B terminal is energized on a call for heat.  
Economizers (Subbases with Auxiliary Relay)  
Mechanical cooling is often used when outside temperatures  
are in the 50°F (10°C) to 60°F (16°C) range and humidity is  
below 50 percent. In central and northern climates, hundreds  
of hours fall into this temperature category. By permitting 80 to

An economizer is used to take advantage of the outside air.  
The typical economizer consists of an outside air damper,  
motor, outdoor air changeover control and a minimum position  
potentiometer. The motor controls the dampers. Suitability of  
the outside air for cooling is determined by the outdoor air  
changeover control. The potentiometer is used for adjusting  
the minimum position of the economizer dampers, which  
provide a minimum amount of fresh air for ventilation.

The economizer reduces compressor run time, thereby saving  
energy and extending the compressor life. The drawback to  
using the economizer is that during the Unoccupied period, if  
there is no call for cool or outdoor air is not suitable for free  
cooling, the economizer is controlled to minimum position.  
This position allows some percentage of outdoor air to enter  
the building, regardless of air suitability. The situation can  
cause the heating or cooling to run more often than if suitable  
outdoor air is permitted to enter the building.  
When the system is calling for cool or is de-energized, but  
the last function was cool.  
When the last function was heating, the operation is the  
same as Auto (Heat). If the last function was cooling, the  
operation is the same as Auto (Cool).  
FAN OPERATION  
When the fan is set to On, the fan is energized continuously in  
the Occupied period. The Auto setting energizes the fan with  
the heating or cooling system. If the subbase is Q7300D, the  
fan cycles with Y1 and W1 during Unoccupied period.  
The thermostat can take advantage of an economizer by  
connecting the subbase auxiliary relay contacts (A1 and A2)  
to control the economizer minimum position potentiometer.  
The contacts close during the Occupied period, allowing the  
economizer to operate normally. The contacts open during the  
Unoccupied period, disabling the minimum position feature of  
the economizer. The open contacts cause the economizer to  
drive dampers fully closed instead of staying at minimum open  
position. This reduces the possibility of unsuitable outdoor air  
from entering the building, which lowers the internal load on  
the HVAC system and saves additional energy.  
EMERGENCY HEAT (SELECT T7300 THERMOSTATS ONLY)  
With the system set for Em Heat, auxiliary heat serves as  
stage one; compressor stages are locked off. The fan cycles  
with the auxiliary heat.  
COMMUNICATING SUBBASE  
Select T7300F Thermostats with the Q7300H Communicating  
Subbase are designed for conventional or heat pump  
applications in a LonWorks® network. The Q7300H Subbase  
allows remote access and the sharing of clock, schedule,  
setpoints, bypass and other system parameters in a  
LONWORKS® network. See Fig. 33 for a T7300F/Q7300H  
wiring layout in a LONWORKS® network.  
Other Uses for the Auxiliary Relay  
Examples of other uses of the auxiliary relay are hot water  
heaters, lighting or baseboard heat. The additional loads are  
connected to the auxiliary relay contacts on the subbase. The  
contacts are rated for 1.6A at 30 Vac, but can be adapted to  
higher current applications with the use of an external relay  
and transformer. See Fig. 19.
