Installation Instructions
Installation
Overview
The TH193 HC 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 are also
available separately as orderable accessories. See
TB 237 (155-244P25).
NOTE: 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. See Piping for
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
keyholes 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.
