Figure 7 – Connections for single stage thermostat for zone control systems
CONFIGURATION
¾ The “System Type” for this thermostat must be set to “Zone Control” under “System Options”.
The two additional outputs (W2 and Y2) are use with zoned heating and cooling systems. The W2 and Y2
terminals control the mode of operation (heating or cooling) of the zone control panel. The zone control panel
will recognize calls for heat (W) from the individual zones when the W2 terminal is energized, and calls for
cool (Y) when the Y1 terminal is energized. Neither W2 nor Y2 is energized when the mode is set to "OFF".
Therefore, the RC-2000 can act as a Master to set the operating mode of the entire system.
POWER UP
1. Double check wiring, be sure that there are no stray wires or wire strands at the connections.
2. Connect power to the transformer and system. The display will show the current thermostat settings.
3. Press [FAN] and select “On”. The fan should come on.
4. Press [FAN] and select “Auto”. The fan should go off.
5. Set the Mode to "Heat". Raise the desired heat setting above the current temperature. Ensure that the
heating unit comes on. Set the mode to "Off". Ensure that the heating unit goes off.
6. Set the Mode to "Cool". Lower the desired cool setting below the current temperature. Ensure that the
cooling unit comes on. Set the mode to "Off". Ensure that the cooling unit goes off.
