IC961 double stage electronic controller with defrost

IC 961 controllers are electronic two-step devices with defrosting functions. The IC961 controller has an analogue input for NTC temperature probes (parameter selectable PTC) and two voltage-free digital outputs on relays for control of heating and cooling functions in the cooler. The defrost cycle is time-controlled by disabling the relay used for cooling.

The value read by the probe is shown on the display with three digits plus the minus sign. Reading with a decimal point is parameter-programmable. The buzzer is optional. All versions have a TTL connection so that the Copy Card quick programming accessory can be used.
