6.21    HOT WATER CONTROL MODE

WARNING:

 modification and/or setting of these functions and these pa-

rameters must only be carried out by authorized personnel possessing the 
necessary technical skills to install and service these units. Incorrect set-
tings may lead to malfunctioning or damage to the unit and the system! An 
incorrect setting may lead to not reaching the set-point, prolonged times 
or excessive absorption.

At the commissioning parameter setting page, by touching “Hot water control 
mode”, it can be set to “Auto” or “Manual”.
When it is set to “Manual”,"Running Frequency Setting" can be set, and the user 
could change the parameter to fix the frequency of the compressor in the "Hot wa-
ter" mode, otherwise, the unit will automatically run based on the original logic. 
After that, this setting will be saved by touching the “Save” icon.

Hot water control mode

Hot water control mode: Manual

Running Frequency Setting: 50Hz

 

Note: If the relative function is activated (paragraph "8.1 Activating/deactivating 
the memory (On/off memory) p. 32"), the value of these parameters will be stored 
in the memory and automatically reset after any possible voltage failure.

6.22    SG FUNCTION (SMART GRID)

It is allowed to be activated only when the control panel is tu rned off. When it has 
been activated, the operating main unit will receive and execute control commands 

from the smart grid, except when the control panel has been turned off. See the 
table below for the SG control commands.

6.23    COOL CONTROL MODE

When it has been activated, it will limit the highest frequency of the compressor for 
cooling operation.

6.24    HEAT CONTROL MODE

When it has been activated, it will limit the highest frequency of the compressor for 
heating operation.

6.25    HIGHEST WATER PUMP SPEED LIMIT FUNCTION

When it has been activated, there are three options for the highest speed of the wa-
ter pump, “High”, “Medium” and “Low”. “High” is for the speed level 10, “Medium” for 
level 9 and “low” for level 8. Once it has been set, the operating speed of the water 
pump is not allowed to exceed this set value.

6.26    WATER PUMP ANTISTALL

When it has been activated, it allows to set the antistall interval and antistall dura-
tion for the water pump. Once the main unit has been turned off, the water pump 
will run at the highest speed for antistall duration every antistall interval so as to 
prevent the water pump from being damaged.
