ON position
Example 1: Two-Stage Cooling and Heating -
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-CA100 simulating multiple stage operation using temperature differential
based on W1 / Y1 call and run time.
