the refrigerant liquid line between the air coil
and the electronic expansion valve.
Air Coil Vapor – displays the temperature of the
refrigerant vapor line between the heat/cool
reversing valve and the air coil.
HW Coil Liquid – displays the temperature of
the refrigerant liquid line leaving the potable
water heat exchanger.
– Refrigerant Valve Diagnostics
RV1 status – displays the status (on–DHW or
o –no DHW) of the RV1 (potable water heating)
reversing valve. (QE models only)
RV2 Status – displays the status (on–cooling,
or o –heating) of the RV2 (heat/cool) reversing
valve.
Water Coil EEV1 Stat – displays the status (on or
o ) of the heating electronic expansion valve.
Water Coil EEV1POS – displays the position of
the heating electronic expansion valve in steps.
0=fully open, 1040 = fully closed.
Air Coil EEV2 Stat – displays the status (on or
o ) of the cooling electronic expansion valve.
(QE models only)
Air Coil EEV2POS – displays the position of the
cooling electronic expansion valve in steps.
0=fully open, 1040 = fully closed. (QE models only)
– Miscellaneous Diagnostics
Control Voltage – displays the unit’s control
voltage.
Cabinet Ambient – displays the ambient tem-
perature in the unit’s compressor section.
Ht of EXTR/REJ – displays the amount of heat of
extraction (heating) or heat of rejection (cool-
ing) to/from the loop depending on mode of
operation.
Unit Power – displays the instantaneous power
consumption of the unit.
COP/EER – displays the current operating ef-
ciency of the unit (COP for space heating, EER
