Programmable Heat Pump Thermostat  
INSTALLATION INSTRUCTIONS  
4.  
After installation is complete, check out product  
operation as provided in these instructions.  
APPLICATION  
The T8011R Heat Pump Thermostat provides 24 Vac  
control of a two-stage heating and one-stage cooling heat  
pump system with manual changeover from heat to cool.  
First stage heating and cooling cycle rates are fixed at 3  
cph. Second stage heating cycle rate is selectable at  
CAUTION  
Can damage heating/cooling system.  
Disconnect power at furnace or main breaker/fuse  
box.  
Hazardous Voltage  
3, 4, 5, 6, 9 or 12 cph. Temperature indication can be set  
for °F or °C.  
The T8011R Heat Pump Thermostat is powered directly  
from the system transformer. Setpoints are held perma-  
nently in memory and retained during power outages.  
Location  
Install the thermostat about 5 ft (1.5m) above the floor in  
an area with good air circulation at average temperature.  
See Fig. 1. Do not install the thermostat where it can be  
affected by:  
The T8011R model includes a thermostat, wallplate and  
owner’s guide. A 7 3/8 in. (188 mm) x 5 3/4 in. (146 mm)  
decorator cover plate (for covering wall marks) is available  
separately. Order Honeywell part no. 209649A (taupe) or  
part no. 209649B (white).  
drafts or dead spots behind doors and in corners.  
hot or cold air from ducts.  
radiant heat from the sun or appliances.  
concealed pipes and chimneys.  
unheated (uncooled) areas such as an outside wall  
behind the thermostat.  
MERCURY NOTICE  
If this control is replacing a control that contains  
mercury in a sealed tube, do not place your old  
control in the trash. Dispose of it properly.  
Mounting Wallplate to Wall  
IMPORTANT  
Contact your local waste management authority for  
instructions regarding recycling and the proper  
disposal of a control.  
Level for appearance only. The thermostat  
functions normally even when not level.  
Mount wallplate and the T8011R with the screws provided  
(
see Fig. 2) as follows:  
1.  
2.  
3.  
Place the wallplate at the desired location on the  
wall.  
Pull the thermostat wire through the wallplate  
entrance hole.  
Fasten the wallplate to the wall using the anchors  
and screws provided.

3.  
Read these instructions carefully. Failure to follow  
them could damage the product or cause a hazard-  
ous condition.  
Check the ratings given in the instructions and on  
the product to make sure the product is suitable for  
your application.  
4. After wiring the wallplate, plug the hole with non-  
flammable insulation to prevent drafts from affecting  
the thermostat; see Wiring section.  
Installer must be a trained, experienced service  
technician.
