REVERSE OPERATION Digital Input
If the REVERSE OPERATION digital input (terminals 35/36)
is active, the appliance controller signals that the circuit is in
the REVERSE mode.

Sensor Locations
The firmware of the SHC Controller supports sensors
mounted in positions 1, 3, 6, 7, 9, 14, 17, and 20 defined in
Table 8.
NOTE: The max. permissible number of connected sensors
at the same time is 6.

pos. description
1 tE1 Evaporator fluid supply temperature
in REVERSE mode
3 tSole1 Evaporator air inlet temperature
6 to2 Suction line temperature
7 to1 Evaporating fluid supply temperature
9 tV2 Condenser fluid supply temperature
14 pV2 Condenser fluid supply pressure
17 po2 Suction line pressure
20 dp Evaporator air differential pressure
NOTES:
Sensors and secondary (output) of transformer cannot be

grounded simultaneously.
 Sensors with current output 4...20 mA and ratiometric vol-
tage output 0.5 V...4.5 V cannot be used simultaneously.

OEM SHC CONTROLLER – INSTALLATION INSTRUCTIONS
 Connecting sensors by wires longer than 6 m might
decrease the accuracy of measured values.
 If sensor setting is made wrong, the controller will signal
configuration error.
