T8011R
Programmable Heat Pump Thermostat
INSTALLATION 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
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 permanently in memory and retained during power outages.
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).
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.
Contact your local waste management authority for
instructions regarding recycling and the proper
disposal of a control.
INSTALLATION
When Installing this Product…
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for
your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
Hazardous Voltage
Can damage heating/cooling system.
Disconnect power at furnace or main breaker/fuse
box.
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:
— 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.
Mounting Wallplate to Wall
IMPORTANT
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. Place the wallplate at the desired location on the
wall.
2. Pull the thermostat wire through the wallplate
entrance hole.
3. Fasten the wallplate to the wall using the anchors
and screws provided.
4. After wiring the wallplate, plug the hole with nonflammable insulation to prevent drafts from affecting
the thermostat; see Wiring section.

Wiring
IMPORTANT
Use 18-gauge maximum wire for wiring the
T8011R Thermostat.
All wiring must comply with local electrical codes and
ordinances. Disconnect the power supply to prevent
electrical shock or equipment damage.
The shape of the terminals permits insertion of straight or
wraparound wiring connections; either method is acceptable. A letter code is located near each terminal for
identification. See Fig. 3.

OPERATION
Setting FAN and SYSTEM Switches
Fan and system settings are controlled manually by using
the switches located at the bottom of the
thermostat case. See Fig. 7.
FAN Switch
Fan switch settings are:
On: The fan runs continuously. Use for improved air
circulation and air quality.
Auto: Normal setting for most homes. The fan starts
and stops with the equipment.
Slide the FAN switch in the lower left corner of the
thermostat to select the desired fan setting.
SYSTEM Switch
System switch settings control thermostat operation as
follows:
Cool: The thermostat controls the cooling system.
Off: Both heating and cooling are off.
Heat: The thermostat controls the heating system.
Em. Ht.: The thermostat cycles auxiliary heat (W2) and
emergency heat relay (E) as needed to maintain
setpoint. Terminal L is energized continuously (fault
heat relay is on continuously). Cooling system is off.
Compressor is de-energized.
Slide the SYSTEM switch in the lower right corner of the
thermostat to select the desired system setting.
