.3 Remote Input Wiring

Heating Cycle Selection (switches #1 and #2)

The TH140 is equipped with a remote input which allows connection

of a telephone controller (optional Aube CT240), a home automation

system or any other remote control system. When a signal is

received through this input, the TH140 will automatically switch from

normal operating mode to Vacation mode, or vice versa when the sig-

nal is removed.

Select the cycle using switches #1 and #2. Short cycles help

eliminate temperature variations, thus increasing user comfort. Since

shorter cycles can lead to premature system wear, it is important to

select the temperature control cycles appropriate to your heating

system. In general, the bigger your heating unit is, the longer the

cycles should be.

Select the span using switches #1 and #2. The default temperature

span is 0.5°C (0.9°F). For example, if the temperature setpoint is

20°C (68°F), the heating system will turn on at 19.5°C (67.1°F) and

turn off at 20.5°C (68.9°F).

.4.1 Proportional Adaptive Mode (switch #5)

(0,9°F)

This mode analyzes previous cycles to define the the next duty cycle.

This control mode guarantees optimal temperature control based on

the system’s capacity. To extend the life of the system, a minimum

On/Off time of 10% of the cycle has been implemented. For example

with a 15-minute cycle, the system would not start or stop for less

than 1.5 minutes.

Ideal for:

Circulator control in a hot water system

Electrical hot-air furnace

Conventional gas or fuel hot-air furnace

Not recommended for:

•

Gas or fuel furnace or boiler with a wall chimney having a 30-sec-

ond or higher combustion gas purging cycle. To figure out the gas

purging cycle of your system, count the time between the heating

command sent by the thermostat and the moment when the

burner actually goes on.

•

Multi-zone systems, where several thermostats command a single

heating unit.

Note: In these last two cases, conventional mode with anticipation is

recommended.
