NOTES:
— If auxiliary output is used to toggle occupancy of the electronic control card inside the equipment, configure
the relay parameter (Aux cont) to the N.O. setting. A second relay can be added for additional functionality of
the occupancy output.
— If the same power source is used for the heating stages, install jumper across RC and RH. Maximum current
is 2.0 amps.
— Economizer output uses a half bridge rectifier. Reference of the control signal is the common of the power
supply of the thermostat (terminal C).
— Electromechanical contacts are to be used with the digital inputs. Electronic triacs cannot be used as mean of
switching for the input. The switched leg to the input for the input to activate is terminal C (common).
— The transformer of the unit provides power to the thermostat and the additional loads that will be wired to the
thermostat.
