6.1 SETTING THE CONTROL LOGIC CTRL.STATE
At the commissioning parameter setting page, by touching “Ctrl. state”, it can be set
to “T-water out” or “T-room”.
Ctrl. state
T room
T water out
OK Cancel
After accessing the “Ctrl.state” function, you can choose whether to base the unit
control logic on the processed water temperature or on the ambient air temper-
ature (if the air probe accessory is installed and correctly set). Select the required
logic, then press “OK” to conrm.
 Note:
— If the ambient air probe accessory is not installed (and correctly set), you can
only choose “T-water out”;
— If the relative function is activated (paragraph "8.1 Activating/deactivating
the memory (On/o memory)p.32"), the value of these parameters will be
stored in the memory and automatically reset after any possible voltage failure.
6.2 SETTING THE STATUS OF THE 2WAY VALVE IN
COOLING MODE COOL 2WAY VALVE
Cool 2 way valve

O
OK Cancel
After accessing the “Cool 2-Way valve” function, you can set the status of the 2-way
valve in cooling mode (for more information about the assembly and use of the
2-way valve, refer to the installation manual). Select the required logic, then press
“OK” to conrm.
It is optional. When there is a radiant oor system and radiators, it can be used to
control the system.
 Note:
— If you select the “O” status, the valve will be CLOSED in cooling mode; it will be
OPEN if you select “On”;
— If the relative function is activated (paragraph "8.1 Activating/deactivating
the memory (On/o memory)p.32"), the value of these parameters will be
stored in the memory and automatically reset after any possible voltage failure.

Heat 2 way valve
After accessing the “Heat 2-Way valve” function, you can set the status of the 2-way
valve in heating mode (for more information about the assembly and use of the
2-way valve, refer to the installation manual). Select the required logic, then press
“OK” to conrm.
 Note:
1. If you select the “O” status, the valve will be CLOSED in heating mode; it will
be OPEN if you select “On”;
2. If the relative function is activated (paragraph "8.1 Activating/deactivating
the memory (On/o memory) p. 32"), the value of these parameters will
be stored in the memory and automatically reset after any possible voltage
failure.
