heat).
FW2: 2 pipe fan coil unit with back-up electric heat
(requires a pipe temperature sensor to detect
seasonal water temperature change over).
FC2: 2 pipe fan coil unit without back-up electric heat
(requires a pipe temperature sensor to detect
seasonal water temperature change over).
PAC:
PTAC unit.
HbW:Heat Pump B with W2 assist (default
compressor signal (Y) is cooling, reverse valve and
compressor signals (B + Y) required concurrently
for heating. When applicable, 2nd stage heat signal
(W2) is engaged in addition to compressor and
reversing valve (B+Y+W2). Use this HVAC type
also for Heat Pumps B without 2nd stage heat.
HpB: Heat Pump B with W2 replace (default
compressor signal (Y) is cooling, reverse valve and
compressor signals (B + Y) required concurrently
for heating. When applicable, 2nd stage heat signal
(W2) is engaged by itself, releasing the compressor
(Y) and reversing valve (B) signals.
HoW:: Heat Pump O with W2 assist ( default
