Tech
activation. When the temperature is below the set value, the device is inactive
whereas when the temperature exceeds this value, the device is enabled.
•
Hysteresis – the temperature difference between device activation and its
deactivation (e.g. when the activation threshold is set to 60ºC and the
hysteresis value is 3ºC, the device will be activated when the temperature
reaches 60ºC and it will be disabled when the temperature drops to 57ºC).
•
Sensor – this option is used to select which sensor will provide temperature
information needed for the operation of the device connected to the additional
contact.
IV.c.2) DHW
This option should be selected when DHW pump is connected to the controller.
•
Activation threshold – this option is used to set the temperature of device
activation. When the temperature is below the set value, the device is inactive
whereas when the temperature exceeds this value, the device is enabled and
operates until the set temperature is reached.
•
Hysteresis – this option is used to set the hysteresis of the set temperature.
After the set temperature is reached, the device is switched off. It is switched
on again after the temperature on the sensor drops below the set temperature
minus hysteresis value (e.g. when the set temperature is 60ºC and the
hysteresis value is 3ºC, the device will be switched off when the temperature
reaches 60ºC and it will return to operation when the temperature drops to
57ºC).
•
Set temperature - This option is used to define the set temperature.
•
Maximum temperature – this option is used to set the maximum temperature
– when this temperature is reached, the device is switched off.
•
Sensor 1 - this option is used to select which sensor will provide temperature
information needed for the operation of the device connected to the additional
contact (activation threshold).
•
Sensor 2 - this option is used to select which sensor will provide temperature
information needed for the operation of the device connected to the additional
contact. (set temperature).
IV.c.3) Room regulator
This option should be selected if the device connected to the additional contact is to
operate using the signal from the room regulator. When the regulator has not
reached the set temperature – the contact is closed (the device is active). After the
temperature has been reached, the contact opens (the device is switched off).
It is possible for the additional device to work according to the signal from the
maximum of 4 room regulators. Then, the device will switch off only when each of
the regulators signals that its set temperature has been reached.
