Example 1: Conventional Two-Stage Cooling and Heating -
V1 operates in dual stage heat / cool mode using thermostat signals W1, W2, Y1, Y2, and fan signal (G). G1, G2 and G3 are
available but not required.
Example 2: Single-Stage Operation-
If Y2 or W2 is left unconnected or is unavailable from the thermostat
set SW1-1 to the ON position.
RMF-CA200-V1 simulating multiple stage operation using temperature
differential based on W1 / Y1 call and run time.
Example 3: Heat Pump Mode Operation -
If Y2 or W2 is left unconnected or is unavailable from the thermostat
set SW1-1 to the ON position.
RMF-CA100-V1 simulating multiple stage operation using temperature
differential based on W1 / Y1 call and run time.
Default OFF position configures conventional mode, ON position enables Heat Pump mode
