Description
JP1
TRIAC Output Signal
Selector
A&B = Internal: All TRIAC output signals are linked to internal 24 Vac (same as thermostat).
B&C = External: All TRIAC output signals are linked to external 24 Vac (different than thermostat).
JP2
Digital Output Signal
Selector
A&B = Internal: All digital output signals are linked to internal 24 Vac (same as thermostat).
B&C = External: All digital output signals is linked to external 24 Vac (different than thermostat).
JP3
Mode Selection
A&B = RUN: Thermostat is in Operation Mode. (See Operation Mode Operation Modepage 13)
B&C = PGM: Thermostat is in Programming Mode. (See Programming Mode, page 4)
JP4
Fan Output Signal Selection A&B: Pin 10 of TB1 is set to digital output signal (DO3). (See Step 33)
B&C: Pin 10 of TB1 is set to analog output signal (AO4). (See Step 33)

Mounting Instructions
CAUTION: Remove power to avoid a risk of malfunction.
A. Remove the captive screw that’s holding the base and the front cover of the unit together.
B. Lift the front cover of the unit to separate it from the base.
C. Pull all wires through the holes in the base.
D. Secure the base to the wall using wall anchors and screws (supplied). Make the appropriate connections.
E. Mount the control module on the base and secure using the screw.
