Tab. 7.a
Notice: in Off status, the defrost interval dI is always updated, in order to maintain the cyclical nature of this interval. If a de-
frost interval expires when the unit is off , the event is recorded and, when the unit is switched on, a defrost request is generated.
The transition from On to Off occurs as follows:
• the compressor protection times are observed;
• pump down is performed (if enabled);
• defrosting is forcibly terminated and will not resume when switching On;
• the continuous cycle is forcibly terminated and will not be resumed when switching On.
The transition from Off to On occurs as follows:
• the compressor protection times are observed;
• defrosting is not performed at start-up (if enabled), this in fact refers to power-on;
• the compressor and fan delay at start-up c0 is not set, and refers to power-on.
7.2 Inputs and outputs
The iJW controller has a maximum of 3 analogue inputs, 2 digital inputs and 1 multifunction input. In addition, on some models,
an additional analogue input is available for connecting a humidity probe. iJW has a maximum of 6 digital outputs. See “De-
scription of the terminals”. NTC, PT1000, PTC, NTC HT or NTC LT temperature probes can be connected to the analogue inputs; all
probes must be the same type. See the parameter table.
