Upon arrival the front lobby/Bar system was displaying 80° indoor temperature set to 72 in cooling Initial roof inspection found the system running in high stage heating and short cycling on primary limit with a confirmed call for stage 1 and stage 2 cooling at y1 and y2 of the RTRM Suspect possible intermittently failing RTRM or faulty ignition module relay failing to disengage heating mode After power cycle and multiple retries through hot wires and thermostat demands the system is running normal in cooling mode. And the thermostat has lowered from 80 indoor to 72 with a new set point of 68 If system fails to cool again the RTRM will need replaced
