• Hy: Hysteresis band (or dead band). This parameter is valid only on/off control mode. In
the on/off heating mode, the controller will stop sending power to the heater when
temperature T is above the set value (SV), and start sending power again to the heater if
T drops below (SV-Hy). For example, if SV=100 °C. Hy=3 °C, the heater will be turned off
when the temperature rise above 100 °C; it will be turned on again as the temperature
drops below 97 °C. For the on/off cooling mode, the compressor will be turned off when
T<SV. It will be turned on again when T>SV+Hy.
• AS: Anti-short cycle delay. The Anti-short is the delay time to turn on the cooler (E.g,
refrigerator). If the cooler is compressor based, compressor should not be turned on
immediately when it is at high pressure (just after turned off). Otherwise, it may shorten
the life of compressor. The anti-short cycle delay function can be used to prevent the
rapid cycling of the compressor. It establishes the minimum time that the compressor
remains off (after reaching cutout) before turns on again. The delay overrides any
controller demand and does not allow the compressor to turn on until the set delay-time
has elapsed. It gives time to release the refrigerant pressure through evaporator. It
typically set to 6 (minutes). The unit is in minutes. This setting is only valid for cooling
mode control.
