RTRM board flashing code 2 "system lockout" Reset the power, heat came on immediately. Space got from 65⁰ to 71⁰ in roughly 45 minutes System has two heating stages and two cooling stages. Both were wired to run only in high heat or high cooling Changed the wiring and the thermostat setup for 2 heat and 2 cool control. Coils are clean Filters are OK Blower running normally Cannot find any issues with the heating side of the unit. It is too cold outside to run the cooling mode today and test for proper operation.
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

Replace both drain pans on RTUs and replace high limit for kitchen unit. Rebuild broken drain trap.
Kitchen thermostat was set to 64 degrees and dining room was set to 70. Both were indicating 70 degree room temperature. Thermostats were also set to follow a schedule. Put them both on a permanent hold. Got on the roof, both units are heating normally at this time. Possible misread of set point and room temperature on the thermostats.
Replace both heat exchangers for the RTU units at Harvest Quote two new drain pans, and a new limit for kitchen unit standing on filter sides of unit the right one.
Upon arrival was informed of RTU2 fire alarm went off minutes before arrival. Did not discover any causes or concerns on smoke alarm circuit, RTU on West side needs the heat exchanger replaced, unit has began forming holes in the bends and is becoming unsafe to operate. Installed CO detector in harvest by the bathrooms. Quote for heat exchanger is currently being discussed with Justin.
