Room Thermostat Installation - 3100/4100 Series

IMPORTANT

Low voltage wires MUST never enter any line voltage enclosure.

Description

A low voltage room thermostat is required for room temperature control with the Comfort Plus. Any room thermostat used with this system must be 24 VAC. (Contact the factory for more information on the thermostats available from Steffes.)

Optimal placement of the room thermostat is on an interior wall in the main living area where it is not affected by direct sunlight or other abnormal temperatures. A location near a cold air return may provide best air temperature sampling.

Route Low Voltage Wires

Disconnect power to the Comfort Plus and route low voltage wire between the thermostat and the Comfort Plus system.

Insulate the Wall Opening

Insulate the wall opening through which the thermostat wires run. Failure to do so may affect the accuracy of the thermostat.

Attach Thermostat

Attach the thermostat to a wall. If the thermostat has an anticipator, set it to .1 amps.

Route Wiring into Electrical Compartment

Route the low voltage wire into the electrical compartment of the Comfort Plus through one of its low voltage wire knockouts and to the system’s twelve (12) position low voltage terminal block.

NOTE: Never install any wiring in the line voltage compartment of the Comfort Plus unless it is rated for line voltage.
