F−Compressor High Temperature Limit
(Early Models)
Each scroll compressor in the HS26−261, −311, −411, −461
is equipped with a compressor high temperature limit lo
cated on the outside top of the compressor. The sensor is a
SPST thermostat which opens when the discharge tem
perature exceeds 280_F + 8_F (138_C + 4.5_C) on a tem
perature rise. When the switch opens, the circuit to the
compressor contactor and the time delay is de−energized
and the unit shuts off. The switch automatically resets
when the compressor temperature drops below 130_F +
14_F. (54_C + 8_C)
The sensor can be accessed by prying off the snap plug on
top of the compressor (see figure 7). Make sure to securely
seal the limit after replacement. The limit pigtails are lo
cated inside the unit control box. Figure 8 shows the ar
rangement of compressor line voltage terminals and dis
charge sensor pigtails.
