NOTES

 - the HP DHW parameter is available if the system is fitted 

with a heat pump that heats the domestic hot water in the 

storage tank

 - for the HP DHW parameter, there are two time schedules: 

one for winter and the other for summer. select the required 

season (HOT WATER ONLY or HEATING AND HOT 

WATER) from the STATE/BOILER menu, then program the 

HP DHW parameter.

 

WARNING:

 in HOT WATER ONLY, the parameter is factory 

set to keep time schedule active every day of the week 

from 05:00 to 08:00, to prevent continuous heat pump cycle 

reversals if the cooling function is active. If you want to alter 

this setting, contact the
