COMPRESSOR CRANKCASE HEATER
Units are equipped with crankcase heaters that are
rated for the connnected voltage and operate during
compressor off cycle.
DIRTY FILTER SWITCH
Located inside the blower compartment, this switch
measures air pressure differential across the filter (see
Figure 2.19 on page 54). Manual reset only. Default
setting: 0.8"static, 50% blocked filter (approximately).

ZETTLER ISOLATION RELAYS:
WALL-MOUNT UNIT
Black Zettler surface mount relays used in the wall-
mount unit to isolate the start signal from the high
pressure relay circuit (see Figure 2.20 on page 54).
FUSES
5x20mm time delay, glass tube fuse: 250VAC rated
voltage, 35 rated amp interruption at rated voltage.
BATTERIES
Used in wall-mount unit and controller boards, flat-disk
style BR2330 3V battery. Used only for time/date during
complete power loss. Estimated lifespan 7-8 years.
