Installation

Removing Existing Thermostat

1. Remove the existing thermostat from the wall.

3. Place a piece of tape on the supply air line to identify it.
4. Remove the terminal head and the gasket from the fitting.
5. Clean the surface of the fitting, if required.

Installing New Thermostat
See Figure 1 for a typical thermostat installation.

1. The following table lists the figures that correspond to a particular thermostat application. See the appropriate figure to identify the mounting parts.
   Honeywell Thermostat Type| Type of Terminal| Figure Number
   ---|---|---
   TP901A, B| Flush Fitting| 2
   Plaster Back| 3
   HO, HP, TO, TP, TRO900| Surface Box| 4
   Flush Box| 5
   TP931| Flush Electrical Box| 6
   TP970 to TP974| Shallow Wall Box with Plaster Ring| 7
   Deep Wall Box| 8
   TP410, TP910, to TP924, TP933| Flush Banjo| 9
   Mortar Joint| 10
   TP901C| Mullion or Partition| 11
   Terminal Head Removed| 1/8-inch O.D. Copper Tubing| 12
   3/16-inch O.D. Copper Tubing| 13

2. Complete the required air line connections as necessary. Secure all connections and install the plug-in adapters into the 5/32-inch (4 mm) plastic tube. Use the blue adapter  for the supply air line. See Figure 1.
   NOTE: Either polyethylene (hard, black) or polyurethane (soft, clear) tubing is recommended. The appropriate tubing depends on which is most compatible for the application.

3. Place the multi-slotted metal plate into the adapter frame, if required. Attach the multislotted plate to the terminal head or the wall using screws and slots shown in Figures 2 through 13.

4. Loosely screw adapter base to the multi-slotted plate.

5. Draw plastic tubing through the multi-slotted plate and the adapter base. Install the plug-in adapters on the wall plate.

6. Using mounting screws supplied with the thermostat chassis, install the wall plate on the adapter base as follows:
   a. Guide screws through the slotted key holes on the wall plate and partially insert them into the adapter base.
   b. Orient the wall plate so that it is square and level.
   c. Tighten the mounting screws to secure the wall plate in place.

7. Moisten the thermostat supply and return ports to lubricate them. Carefully insert the thermostat ports into the terminal adapter “O” rings on the wall plate.

8. Configure the cover per installation instructions provided and mount the cover over the thermostat.

9. Use either the hex key end of the calibration and cover screw wrench or a 1/16” Allen wrench to tighten the two screws that secure the cover in place.

NOTES:

1. To remove the thermostat from the wall plate, hold the thermostat firmly at the top and bottom and start to pull the thermostat from the wall plate. At the same time, use a screwdriver to pry the wall plate latch arms away from the thermostat chassis and pull the thermostat away from the wall plate.
   Frequent removal and installation of the thermostat can bend the latch arms beyond their operating positions. If this occurs, bend the latch arms back to their operating  positions before mounting the thermostat.
   The installation is complete.
