Description
Default setting & Other possibility
The following parameters are only visible if a water contact sensor (NTC 10K sensor) 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 drawing to install the sensor)
Setting Level to switch your installation between Heat and
cool mode.
When the water temperature (Wtemp) on the incoming pipe
decrease below this setting (minus the hysteresis value/2),
the installation will work in cooling mode.
Wtemp < HCL – HCh/2 => System in cooling mode
Wtemp > HCL + HCh /2 => System in heating mode
Press (OK) to view the instantaneous value measured by
the sensor.
Default: 22°C
Adjustable: 5 to 35°C
Hysteresis value for the setting level “HCL”, to avoid quick
commutations between Heat & Cool change.
Default: 5°C
Adjustable: 3 to 10°C
The following parameters are only visible if a water humidity sensor (NTC 10K sensor or free contact
sensor) is connected and installed on the incoming pipe of the manifolds
(See the schematic and system drawing to install the sensor)
Setting level to switch off the cooling function to avoid
residual humidity in the house:
When the water temperature in the pipe decrease under this
level during the time of the anti short cycle adjusted on “rHt”
the cooling function will be stopped.
Press (OK) to view the instantaneous value measured by
the sensor.
Default: 18°C
Adjustable: 5 to 25°C
Minimum time to decide to stop the cooling function when
the water temperature decreases under the “rHL” level.
Default: 5°C
Adjustable: 3 to 10°C
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.
Default: 60 s
Adjustable: 0 to 240s
Press (OK) during 5 seconds to reset the installation.
All parameters are replaced by default value.
Press (OK) on this parameter to exit the parameters menu end come back to the main
display.
7. RF ALARM
- You could see the RF alarm on the Master (Red blinking LED on the concerned zone) and on the RF main
zone programmer (in the status line).
- If a RF alarm is detected on one zone, the regulation will be maintained on this zone by average of the actual
room temperatures of the other zones used on the Master.
- Check the thermostat batteries of the concerned zone. If batteries thermostat must be changed, always
replace the 2 batteries in the same time. The RF alarm message should be disappear alone when batteries will
be replaced.
Note:
If all zones are in RF alarm (Red blinking) check the RF antenna connection before replacing of all thermostat
batteries.
