- STEP 2: Setting DIP Switches On the PCB, there is a 10-position DIP switch for configuration setting. Each position has two states: ON or OFF. The DIP switch inputs are identified by their reference designator on the PCB followed by their switch position.
OFF position
(Default)
Default OFF position configures conventional mode, ON position enables Heat Pump mode
Select Conventional or Heat Pump Mode using Dipswitch 1-2
Single-Stage Operation- Dipswitch 1-1 set to ON position
If Y2 or W2 is left unconnected or is unavailable from the thermostat set SW1-1 to the ON position. This configures single stage operation of RMF-
CA200-V1(A) simulating multiple stage operation using temperature differential based on W1 / Y1 call and run time.

Example2:
Conventional Two-Stage Cooling and Heating -
Dipswitch 1-1 set to OFF position (default position)
RMF-CA200-V1(A) 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 3: Heat Pump Mode Operation - Dipswitch 1-1 set to ON position
If Y2 or W2 is left unconnected or is unavailable from the thermostat set SW1-1 to the ON
position. This configures single stage operation of RMF-CA100-V1(A) simulating multiple
stage operation using temperature differential based on W1 / Y1 call and run time.
In single stage operation Y2, W2 and W3 signals
are not used
