FP Freeze Protection Engaged. Room temperature falls below 40 ° F as measured by a wireless remote thermostat or indoor ambient thermistor activated sensor. no action required. This setting will decompose when room temperature rises above 43 ° F.

Fd front desk switch is off. All outputs are off. Open the front desk switch to allow the occupying unit to operate.

EO Un-Configured Service Board – All operations are conducted for configuration. Enter the configuration menu and set “C3” for the cooler with “H” for electric pumps or heat pumps.

EH Emergency Hydronic Engaged. The EHH switch is off. The compressor is turned off. Allow open front emergency hydronic switch to occupant unit operation.

LS load shedding attached. The LS switch is off. The compressor and electric heat are switched off. Open load shedding switch to allow operation of occupancy unit.

ON The control is configured to respond to a wired thermostat. No action if a wired thermostat is being used. Otherwise, see configuration settings.

OP Open Door Lockout (DS1 and DS2 Open; Wireless). Locked room door. With the door open, the unit will not have space.

NP window switch lockout – (LS and INN open). Closed room door or window. The unit will not be in place due to the door or window being open.

HP Heat Sentinel – (WIAT> u3). no action required. This setting will deteriorate when room temperature falls.

Ur un-rated status (EHH & INN or wireless). The front desk needs to be set to Rented Mode (if applicable).

F1 indoor ambient thermistor reads outside the range -20 ° F to 200 ° F and is not readable without a wireless remote thermostat from a wireless thermostat unit control or an indoor ambient thermistor (IAT). F Replace the black indoor ambient thermistor or wireless remote thermostat.

F2 wireless remote thermostat failure. Change the wireless thermostat.

F3 indoor ambient thermistor ranges from -20 ° F to 200 ° F. Replace the Black Indoor Ambient Thermistor.
