Circulators antiblocking
In the case that circulators C1 or C2 have not been activated for a superior period of time (in hours) to the value selected in the parameter, the
corresponding outputs will be activated with the signalling of their corresponding led, for the same time (in seconds) to the value selected in
the parameter, while the display will show the code. This function is also active with the device in STAND BY mode.
De-icing
When the temperature of the sensor is lower than the value selected in the parameter, the following conditions will be verified:
-
See on the display the alarm state
-
Activation of circulator C1 and its led
The return to the normal operation conditions is made by increasing the temperature over the parameter, increasing a fixed hysteresis of 4ºC.
Over-temperature
When the temperature of the sensor passes the value selected in the parameter, the following conditions will be verified:
-
See the current temperature flashing
-
Activation of the circulators C1 and C2 of the diverter valve and the AUX output and the corresponding led.
-
Activation of the acoustic signal in card IOC-S or in the switchboard HID FIRE BASIC.
By pressing briefly any button, you will be able to turn off the acoustic signals that will be reactivated after 5 minutes if the alarm condition
continuous.
The return to the normal operation conditions is made by decreasing the temperature under the parameter.
Security temperature
When the temperature of the sensor passes the value selected in the parameter, the following conditions will be verified:
-
See on the display the current temperature.
-
Deactivation of the diverter valve and its led.
The return to the normal operation conditions is made by decreasing the temperature under the parameter.
The security function is disabled from the manufacturer. The modification in the INSTALLER MENU allows to limit a temperature predefined
(the parameter) the integration of SHW of the heating chimney in order to avoid any possible over temperature in the output.
Temperature of the others values that are shown.
In the case that the temperature passes over 99.9ºC or it is negative, the display will show the signal
or
with no condition of the
regulation. In the first case the overtemperature function will be activated and in the second case the de-icing function will be activated with
the corresponding signal on the display.
Anomalies
In case of any bad functioning or anomalous situations, the display will show an alarm code as shown in the following table. It is also
indicated how to proceed for the user/fitter to solve the problem.

Interface HID FIRE BASIC remote
In order to allow the user to carry out an immediate verification of the system state and the possible present anomalies, the hydraulic module
must be placed inside the house.
In the case that it is not possible, at least, the switchboard HID FIRE BASIC of the regulator must be connected outside the module or connect
in parallel to the present switchboard another HID FIRE BASIC delivered separately as an optional accessory.
The operation of the regulator keeps as described, and the display and selections of parameters are possible in the same way in any
interface device HID FIRE BASIC installed in the module or from a distance.
