OFF if FS47=1

ON if FS47=0
if CO16=2 (evaporator water pump on if at least a compressor is on), the parameter FS47 allows to
choose if the water pup is on or off in case of domestic hot water production. If the machine has the
domestic hot water valves placed in the gas circuit, in case of contemporary cooling and domestic hot
water production, the evaporator water pump is on.
If only one water pump is needed for cooling, heating and domestic hot water, the evaporator water pump
has to be configured.
Management of the domestic hot water pump
The domestic hot water pump can be turned on continuously (also when the device is on cooling or heating
regulation) or activated only during the production of hot water and during the cycle of legionella as
described in the following paragraphs.
In the case in which the domestic hot water pump is turned on during the production of domestic hot water,
the timing of are the following:
• OUT 1 and OUT 2 outputs switching with the delay of FS27 seconds from pump switching on
• the water pump switching off occurs with the delay of FS28 seconds from OUT 1 and OUT 2 outputs
switching.
The domestic hot water flow switch is managed by parameters AL65
…68.
Domestic hot water flow switch, solar panel flow switch and overload domestic hot water pump.
It is possible to enable the domestic hot water flow switch by setting appropriately parameters AL65..AL68.
It is possible to enable the solar panel flow switch by setting appropriately parameters AL69..AL72.
If
domestic hot water flow switch or domestic hot water pump overload is active, domestic hot water
regulation is disabled; heating and cooling regulation proceed normally.
If solar panel flow switch is active, solar panel regulation is disabled; heating and cooling regulation proceed
normally.
38.3 DOMESTIC HOT WATER SECOND SET POINT
The domestic hot water second set point can enabled by time bands (ES19..ES33 parameters) or digital
input properly configured.
In case of domestic hot water second set point enabled by time bands, the Ichill must have internal clock.

Inside the time band or when the digital input is active to the domestic hot water set point is applied an offset
(parameter ES32) and the new differential for the regulation is ES33.
