Install the room thermostat in accordance with the instruction sheet packed in the box with
the thermostat. Run the thermostat lead wires through control entry opening (Figure 2 or
Figure 17) and connect to the low voltage thermostat connections (see wiring diagram).
Never install the thermostat on an outside wall or where it will be influenced by drafts, con-
cealed hot or cold water pipes or ducts, lighting fixtures, radiation from fireplace, sun rays,
lamps, televisions, radios or air streams from registers. Refer to instructions packed with
the thermostat for “heater” selection or adjustment.
The following is a list of recommended thermostats to be used with or without an econo-
mizer:
