PARAMETER LIST
DIFFERENTIALS
Hy1
Differential1:
(0,1÷25,5°C; 1÷45°F): Intervention differential for set point1, always positive. Compressor1 Cut IN is Set Point Plus
Differential1 (Hy1). Compressor1 Cut OUT is when the temperature reaches the set point1.
Hy2
Differential2:
(0,1÷25,5°C; 1÷45°F): Intervention differential for set point2, always positive. Compressor2 Cut IN is Set Point2 Plus
Differential2 (Hy2). Compressor2 Cut OUT is when the temperature reaches the set point2.

110°C; SET1÷230°F) Set the maximum acceptable value for set point1.
OdS1 Outputs activation delay of section 1 at start up:
(0÷255 min) This function is enabled at the initial start up of the instrument and inhibits
any output activation of the section 1 for the period of time set in the parameter. (Light can work)
AC1
Anti-short cycle delay for compressor1:
(0÷30 min) interval between the compressor1 stop and the following restart.
Con1 Compressor1 ON time with faulty probe1:
(0÷255 min) time during which the compressor1 is active in case of faulty thermostat probe.
With COn=0 compressor1 is always OFF.
COF1 Compressor1 OFF time with faulty probe1:
(0÷255 min) time during which the compressor is off in case of faulty thermostat probe. With
COF=0 compressor is always active.
CH1
Kind of action for section 1: CL
= cooling
