Types of operating modes

Selection of the operating mode is done using the arrow keys (◄) and (►). The cursor must be positioned on the
symbol of the relevant operating mode.
COMFORT mode of operation
Unlimited operation in COMFORT mode
The system runs in constant comfort mode. The ClimaticControl-HC adjusts the flow temperature depend-
ing on the outdoor temperature and the selected curve. No temperature setback.
The display Pos. 5 shows the current flow temperature and the outside temperature at 13 (damped val-
ue). By pressing the button (OK) the preset value of flow temperature appears for about 3 seconds at 5.
At the same time the manually selectable deviation is displayed at 13 (factory setup: 00.0 = no deviation).
Using the buttons (+) or (-) you can adjust the preset value of the flow temperature. If changed, the sym-
bol appears on the display.
In heating mode of operation if no room thermostat is installed ( MuB:  5.3), the circulation pump is
running continuously. The pump switches off if the mixing 3 way valve is closed for the setting time
(PUMP:  System parameters: pump delay time). That is the case when the room heating is sufficient
and the room thermostat closes all heating circuits by means of actuators. The same happens when the
value of flow temperature calculated by the ClimaticControl-HC becomes lower than the actual tempera-
ture value because of rising outdoor temperatures. If the actual value of the flow temperature falls below
the preset value, the pump will restart.
In this case to ensure a correct measure of the water temperature the pump will be start each 30min
for a short time to measure the real temperature of water inside the hydraulic circuit.
To ensure energy saving operating mode of the pump it could be switched by a "pump logic" of a elec-
tric connecting box. The connecting box is normally used together with room thermostats and electro-
thermic actuators. The "pump logic" is a potential free switching relay, the contact of which is closed
whenever higher temperature is demanded in any of the rooms. If all rooms are warm enough, the contact
opens and the pump turns off. ( MuB:  5.5)
If the heat generator / boiler (WE) is in temperature setback and the temperature supplied by the WE
is below the preset temperature calculated by the ClimaticControl-HC, heating mode is not available.
However if the circulation pump is actually running and the 2/3-way valve may also be opened by the 3-
point actuator because of room heating demand, the preset value of flow temperature may be exceeded
for a short period of time when the WE switches to heating mode. In this case, if a temperature limiter is
available, the pump might switch off and then pump operation will be possible only after the temperature
drops below the preset maximum temperature of the TB.
Trouble-shooting: The TB should be installed at a greater distance from the control unit. If necessary you
can set the TB to a higher temperature until the pump starts. After a few minutes of pump operation the
maximum allowable temperature set on the TB should be restored. Alternatively you can remove the TB
from the pipe for a while and leave the pump running for a few minutes. Then refit the TB again to the
pipe.
AUTOMATIC mode of operation
Automatic mode of operation using the built-in or user programs.
The ClimaticControl-HC is controlled according to the selected built-in or user program ( 6.2.).
The flow temperature is controlled depending on the outdoor temperature and the curve with room com-
pensation if RF thermostat is installed. ( 5.3.3 – 5.3.5).
 The room compensation function will be different depending of the RF thermostat installed:
* With WFHTRF-BASIC or LCD (Non programmable thermostat)
The room temperature compensation will be taken in account only during Comfort
gram. During the Reduced
