Operation Section 21
(2) Relay board
• The relay board contains the dip switch, the compressor and fan relays, and a step-down
transformer that reduces the line voltage from 115VAC to approx. 14 VAC. This voltage is
then rectified from 14 VAC to 12 VDC and used for relay coil activation. The 12 VDC voltage
is sent to the control panel assembly, and further being reduced to 5 V for the system logic.
1) Power supply requirements
• This unit requires a single-phase 115 V, 60 Hz power supply.
2) Relay board fuse
• The relay board fuse is the only serviceable component on the relay board assembly. This fuse
provides protection against damage to the step-down transformer. The fuse must be replaced
with the exact same part, or a suitable equivalent.
Specifications:
- 5 A, 250 VAC
CAUTION
Failure to use the exact same fuse may result in damage to the unit and/or components, and will
also void the unit warranty.
