MAX

value

Parameter function

-25°C 45°C

This parameter indicates the outside air temperature corresponding to the maximum

water temperature limit (Sti parameter, P indicator) that can be produced by the com-

pressor.

The adjacent diagram shows the logic

for the dynamic FORCE OFF function;

this logic enables optimal management

of electric in accordance with the unit's

operating heater limits.

Example:

The aim is to produce at domestic hot

water with a setpoint of 55° an air tem-

perature of -10°. Based on the parame-

ters entered in the example, FORCEOFF

will intervene at 45°.

The compressor will continue to work

until an output temperature of 45° is re-

ached. At this point, it will switch itself

off (in compliance with the minimum ON

times) and the electric heater will be

used to bring the system up to 55°C.

WARNING: By setting operating limits

with maximum values the function is di-

sabled and resistance management re-

mains, as explained in the next chapter;

using the FORCE OFF dynamic logic,

integration resistance will be used even

when producing domestic water.
