Eliwell EWCM 4150 - Compressor Timing

No variation in power is required within the PROPORTIONAL BAND. Hysteresis is not included in this algorithm.
All interstep times are resynchronised upon the activation/deactivation of a new compressor combination.
In the case of an regulation probe error, the number of active steps is calculated as a percentage set for the CP21
parameter of the total number of steps.

Compressor timing
The switching on and off of a compressor (inverter or digital) must meet the following requirements:
 Minimum time between switching off/on (parameter CP12). This is the minimum delay between switching off
and switching on;
 Minimum time between switching off/on (parameter CP14). This is the minimum delay between switching on
and switching off;
 Minimum time between switching off/on (parameter CP13). This is the minimum delay between switching on
and switching on again;
