7.2 HOT START
This function is active in heating mode only.
NOTE: PRESENCE OF WATER PROBE (REMOTE) NECESSARY (to install downstream of the valve)
The Hot Start function stops cold air from entering the winter operating environment.
Its involves preheating the exchanger (finned coil) before activation of fans.
Ventilation will only start when the water probe detects a temperature above 35°C.
If this does not occur, it waits for permission from the probe.
If the WATER probe is not present (or is faulty):
● the HOT START is ignored and the fans follow normal temperature control.
LED signalling
While the Hot Start delay is in progress (controlled by the timer or water probe), the red LED (heating) will continue to flash quickly.
Once the delay is over and the fan has started, the red LED remains permanently ON.
7.3 TOO COOL
This function is active in Cooling mode only.
NOTE: PRESENCE OF WATER PROBE (REMOTE) NECESSARY (to install downstream of the valve)
The Too Cool function stops hot air from entering the summer operating environment.
It involves activating the fans when the water temperature is sufficiently cold.
Ventilation will only start when the water probe detects a temperature that is lower than or equal to 25°C.
If the probe is not present (or is faulty):
● ventilation is activated as in normal temperature control.
7.3.1 Blocking Hot-Start and Too-Cool functions from Power–On.
The Too-Cool and Hot-Start functions are disabled by default when powering on for the first time
At the first Power-On, irrespective of the water temperature, the fans operate at the speed set by the fan slider; the Hot-Start and
Too-Cool functions are ignored.
This function allows the installer to test the fans once the machine is installed without having to wait for the water temperature to give
permission for them to be activated.
This block is active for approximately 10 minutes.
When the machine is powered, two cases may arise:
● If power supply is cut off while the time is being counted (within 10 minutes), the counter is reset at the next Power-ON and the fans
operate as described above.
● If the counter goes to zero (10 minutes or more have elapsed), the Hot-Start and Too-Cool functions remain active even if the device is
switched off.
