Disconnect power prior to separating thermostat cover from its base. A. Remove the screw (captive) holding the front cover to the base of the thermostat. B. Lift the front cover of the thermostat to separate it from the base. C. Pull wire through the base hole. 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 (from step A). Settings on PC Board & Connections Mode Selection (JP1) Jumper (JP1) on RUN: Thermostat is in Operation Mode. Thermostat must be set in this mode to operate properly. If not locked, setpoint and control mode (Heating & Cooling ON, Cooling only ON or Heating only ON) can be modified by end user. Jumper (JP1) on PGM: Thermostat is set in Programming Mode. Refer to following section about all settings description TRL54 – 3 wire cable (TB1 #1, 2 & 3) Connect TB1 #6 (A+) & #7 (B-) to EVCB for BACnet service port to work TRL55 – RJ45 Ethernet cable BACnet service port works only if TRL5x is connected to EVCB Recycling at end of life At end of life, please return the thermostat to your Neptronic ® local distributor for recycling.
