Installation Instructions

LOW VOLTAGE WIRING:
Refer to the wiring diagram below for electrical connections. It is recommended that you leave at least 1’ (30 cm) of slack wire at each component wired to ease future servicing.
MAINTENANCE
Suncourt® recommends that you clean your damper at regular intervals to keep it free from lint, dust and debris. The damper must never be exposed to temperatures over
140°F (60°C).
OPERATING INSTRUCTIONS - THERMOSTATIC CONTROL WITH (ZCXXX) NORMALLY CLOSED DAMPER
1. Set the switch on the thermostat marked 'ON-AUTO' , 'ON-OFF-AUTO', 'ON-OFF' or similar wording, to the 'ON or AUTO' position.
2. Heating Season: Set the thermostat to 'HEAT'. Then adjust the thermostat to the chosen temperature (e.g. 55°F) (13°C). As long as the temperature in the room is 55°F
(13°C) or higher, the damper will be closed. If the temperature in the room falls below 55°F (13°C), the damper will open and the room will now receive heated air when the
furnace is running.
3. Cooling Season: Set the thermostat to 'COOL'. Then adjust the thermostat to the chosen temperature (e.g. 85°F) (30°C). As long as the temperature in the room is 85°F
(30°C) or lower, the damper will remain closed. If the temperature in the room goes higher than 85°F (30°C), the damper will open and the room will now receive cooled air
when the central air conditioner is running.

1. Run one wire from either Transformer low voltage
terminal to either terminal on the Damper.
2. Run one wire from the other Transformer low voltage
terminal to the terminal marked “R” on the thermostat.
3. Run one wire from the other terminal on the Damper
to the terminal marked “W” on the thermostat.
4. Connect the terminals “W” and “Y” on the thermostat
together with a short piece of wire (jumper).
5.
Screw the thermostat to the wall.
6. Plug in Transformer to a properly grounded
110/120V receptical.
THE LOW-VOLTAGE WIRING IS NOT POLARITY SENSITIVE. CONNECT EITHER SCREW ON TERMINAL BLOCK TO EITHER SCREW ON TRANSFORMER.
THE THERMOSTAT OR LOW-VOLTAGE SWITCHING DEVICE CAN BE INSERTED ON EITHER SIDE.
UP TO TWO DAMPERS CAN BE POWERED BY EACH TRANSFORMER BY EITHER WIRING BOTH DAMPERS IN PARALLEL TO THE TRANSFORMER TERMINALS,
OR WIRING THE SECOND DAMPER IN PARALLEL TO THE FIRST DAMPER’S TERMINALS.
WIRING INSTRUCTIONS FOR ZONEMASTER™ DAMPERS - USING A DEDICATED LOW-VOLTAGE THERMOSTAT. DO NOT PLUG TRANSFORMER IN UNTIL
