Expected Installation Time

1 hour

Prerequisites

Review all these instructions before you begin installation.
Check job drawings for any site-specific information.
Verify the existing thermostat installation has its supply and return air lines connected properly.

Obtain the installation instructions provided with the thermostat in this Retrostat Kit. The document provides instructions for calibrating the thermostat.
Make certain a supply of wall anchors and plastic ties are available.

Installation

Removing Existing Thermostat

Remove the existing thermostat from the wall.
Plug the supply (main) air line.
Place a piece of tape on the supply air line to identify it.
Remove the terminal head and the gasket from the fitting.
Clean the surface of the fitting, if required.

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

The following table lists the figures that correspond to a particular thermostat application. See the appropriate figure to identify the mounting parts.

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.

Place the multi-slotted metal plate into the adapter frame, if required. Attach the multi-slotted plate to the terminal head or the wall using screws and slots shown in Figures 2 through 6.
Loosely screw adapter base to the multi-slotted plate.
Draw plastic tubing through the multi-slotted plate and the adapter base. Install the plug-in adapters on the wall plate.
Using mounting screws supplied with the thermostat chassis, install the wall plate on the adapter base as follows:
- Guide screws through the slotted key holes on the wall plate and partially insert them into the adapter base.
- Orient the wall plate so that it is square and level.
- Tighten the mounting screws to secure the wall plate in place.
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.
Configure the cover per installation instructions provided and mount the cover over the thermostat.
NOTE: For applications that use the 1/2-inch large set point adjustment knob, align the key hole in the cover over the shaft protruding from the thermostat when mounting the cover (see Figure 1). 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.
Place the optional 1/2-inch large set point adjustment knob on the shaft protruding through the cover. Use either the hex key end of the calibration and cover screw wrench or a 1/16” Allen wrench to tighten the set screw on the knob.

NOTES:

In applications with a 1/2-inch large set point adjustment knob, whenever you remove the thermostat cover, first remove the adjustment knob by loosening its set screw with either the hex key end of the calibration and cover screw wrench or a 1/16” Allen wrench.
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.
