Type of user interface:
Alarm sound if a zone is in Lost Thermostat
Reception Alarm.
Actuator type
Actuator exercise, to avoid grip of the hydraulic
valve. The actuators of each zone will be
activated during 5 minutes at 12h00 if the zone
hasn‟t run since 24 hours.
Main Heat&Cool Actuator exercise, to avoid grip of
the hydraulic valve. The main actuators of the
installation will be activated during 5 minutes at
12h00 if they haven‟t run since 24 hours.
Pump exercise, to avoid grip of the main pump.
The pump will be activating during 1 minute at
12h00 if the zone hasn‟t run since 24 hours.
Delay time (in seconds) for the pump start up after
the first heat demand from minimum one zone.
This function is generally used to avoid noise and
damage of the hydraulic parts of the installation.
Type of control of the main
Heat & Cool actuators.
The following parameters are only visible if a water contact sensor (NTC 10K) is connected and installed on the
incoming pipe of the manifolds, and if the parameter "HC" is on "SenS" position. (See the schematic and system
Setting Level to switch your installation between Heat
and cool
When the water temperature (Wtemp) on the incoming
pipe decreases below this setting (minus the
hysteresis value/2), the installation will work in cooling
mode.
Wtemp < F6A – F6b/2 => System in cooling mode
Wtemp > F6A + F6b /2 => System in heating mode
Press (OK) to view the instantaneous value measured
by the sensor.
Hysteresis value for the setting level "F6A", to avoid
quick commutations between Heat & Cool change.
Description
no: Standard uses
The main actuators will always follow the demand of all zones.
Example: In heating mode, if any zones are in demand the main
heating actuator will be switched off.
Yes: Special uses
