DO NOT locate the thermostat:

•Behind doors, in corners or other dead air spaces.

•In direct sunlight or near lamps, appliances or other sources of radiant heat.

•On an outside wall or wall exposed to an unconditioned space (i.e. garage, etc.).

•In the flow path of a supply register, in stairways or near outside doors.

•On a wall where concealed pipes and/or ductwork will affect the thermostat.

•Near sources of electrical interference such as arcing relay contacts.

WITH REMOTE TEMPERATURE SENSORS

Follow the guidelines for placement of the sensors and locate the thermostat indoors where operating range (see specs) will not be violated (i.e. do not install in a cold garage or hot equipment room). See the sensor installation literature for additional details.

4. DISASSEMBLY

No tools required – use hands to pull the front panel off of the base (Figure 2 ). While holding the base of the thermostat, apply pressure to the base of the latch with your thumb (Figure 3 ).

Both sides have a latch, but it is easiest toFIGURE 2 unlatch one side at a time.

CAUTION: Loss of internal programs may result from static discharge to thermostat circuit board. Installer must touch a grounded metal object before handling the circuit board.
