Installation

Overview

The TH192 DN/DNV thermostat and wall plate mount

vertically to a wall using a variety of rough-in installation

kits (for example, wall box kits or tubing terminal kits). The

ends of the air lines from the rough-in installation kits have

terminal adapters that snap into the wall plate. Terminal

adapters also are available separately as orderable

accessories. (Note that certain retrofit applications allow

air connections directly to the thermostat chassis).

The “S”, “R1”, and “R2” labels on both the thermostat

chassis and the wall plate identify the air line connections.

The thermostat plugs into the terminal adapters on the

wall plate. The Piping section of this document shows

typical connections.

Two cover screws plus latch arms on the wall plate hold

the thermostat in place. The cover fits over the thermostat

and the two cover screws fasten it to the wall plate.

Procedure

The following procedure is for a typical thermostat

installation and assumes the rough-in installation kit is in

place. See Figure 1.

1. The rough-in installation kit provides a supply (blue)

air line and a return air line joined by an air link.

Remove the terminal adapters from the air link and

snap them into the wall plate at their respective

locations.

2. Using the mounting screws supplied with the

thermostat chassis, install the wall plate on the wall as

follows:

a. Guide the screws through the slotted key holes on

the wall plate and partially insert them into wall.

b. Orient the wall plate so that it is square and level.

c. Tighten the mounting screws to secure the wall

plate in place.

3. 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.

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. Use 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. 5.

If the changeover is too high, turn off the supply pressure and rotate the changeover adjust screw clockwise. One turn decreases the changeover point by about 3 psi (20 kPa). Turn on the supply pressure and recheck to verify the new changeover point. b.

Verify that the room temperature is between 70 and 80°F (21 and 27°C). 2. Verify that the supply pressure is 25 psi (172 kPa). Set the night time dial to the room temperature by turning the exposed adjustment knob or using a hex key. Allow the thermostat to stand for about five minutes to adjust to the new setting.
