General Information
Lead/Lag Control (Dual Circuit Only)
Lead/Lag is a selectable input located on the RTRM. The RTRM is configured from
the factory with the Lead/Lag control disabled. To activate the Lead/Lag function,
simply cut the wire connected to J3-8 at the RTRM. When it is activated, each
time the designated lead compressor is shut off due to the load being satisfied,
the lead compressor or refrigeration circuit switches. When the RTRM is powered
up, i.e. after a power failure, the control will default to the number one circuit
compressor.
