7. LOGIC OF OPERATION

7.1 HEAT PUMP ON/OFF STATE:

Activation of the ON/OFF control of the HP present on the USER INTERFACE
and on the KCTR, is subject to closing of the "Remote On/Off" external contact
(connectors 7-8 of the TERMINAL BLOCK).
External contact "Remote On/Off"
OPEN CIRCUIT (connectors 7-8 of the BLOCK TERMINAL)
Feeding electronically heat pump, the display of the USER IN-
TERFACE, appears the word "OFF", and the heat pump can not
yet be on.
In this state, only the "Anti-freeze" function is active
External contact "Remote On/Off"
OPEN CIRCUIT (clamps 7-8 of TERMINAL BLOCK)
Instead of "OFF", displayed is the time or temperature of the
delivery water. It is possible to switch the HP on/off by keeping the
set key pressed set
With KCTR installed (par. 103 = ON), it is also possible to
switch the HP on/off by keeping the down key pressed
down.
Section I :: User
NOTE:
• Following a shutdown due to the opening of the "Remote On/ Off" outer
contact or a power outage, the operating status previously stored in
USER INTERFACE will be reset at the next start-up
• The OFF command to the heat pump involves the complete deactivation
of all aspects of production of cold water, hot water and hot water.
• Compressor start-up consent is obtained only if the water circulator
(Pump 1) is active therefore, in the event of water production request for
heating or cooling of rooms not controlled by KCTR (accessory provided
separately), the relative room thermostat must be connected to "Pump
1" contact (connectors L - K of SC) to activate Pump 1
Heat pump (HP) ON/OFF TIMER:
Once the heat pump has been switched on, its start-up and switch-off can
be automatically set, through the On/Off timer available in the USER
INTERFACE.
This function is enabled by setting the 100=On parameter inside the HP
label menu
It is possible to associate four different profiles of On/Off timer to each
weekday, in particular:
- Profile 1: Four time bands, two On and two Off
- Profile 2: Two time bands, one On and one Off
- Profile 3: Single time band always On
- Profile 4: Single time band always Off
Setting of the time bands of profiles 1 and 2 happens inside the P1 and
P2 label menus.
The association of the various profiles to each weekday happens inside
the dAYS label menu.
NOTE:
If the On/Off timer is active and the set key is pressed for a long time, the
heat pump on USER INTERFACE or KCTR switches off, in both On and Off
time bands. By then pressing the set key for a long time again, the On/Off
timer is reactivated. Therefore, in the On time band the HP switches on
and in the Off band it remains off until change over to On band.
