for water heating fireplace with air intake control (RT-08G)
The regulator controls the intensity of the combustion in the fireplace by adjusting the combustion air damper, so as to maintain the water
temperature in the fireplace to a desired, predetermined level.
This results in enabling the regulator, in a second phase, when the water reaches a predetermined temperature to activate the pump of the
heating circuit (HC) as well as the domestic hot water circulating pump (DHW).
It regulates not only the start and end of the circulators but it also has the option, when the user wishes it, to give a periodic priority to the DHW
pump in correlation to the HC pump. Recurrent priority means that it alternately activates the HC pump for 45 seconds and then suspends it for
the next 4 minutes thus resulting in heating the DHW faster.
It also has the option to shut down another heat source (e.g. gas boiler) when operating the fireplace or to command an additional pump or
motorized valve (solenoid) with a maximum power of 500W.
!
The regulator has an
ANTI-FREEZE
system which protects the heating circuit from potential freezing when the measured temperature is
below 4 o C, by automatically activating the HC pump.
!
The regulator has an
ANTI-CLOG
system which operates the heating circuit pumps for one minute per week during the period that the
device is not used.
The regulator is equipped with its own emergency power source so a power supply interruption up to 8 seconds would not impair its smooth
operation. In case o an outage longer than that, an uninterruptible power supply device can be used (UPS). For safety reasons, if the
regulator is not receiving power, the damper closes completely and is automatically placed in the rest position (fully closed).
7.4.2.1. Using the regulator
All of the regulator functions can be controlled via the control panel (
Pic. 15.1.1
). When the regulator is not operating, the light (
1
)
illuminates amber to notify that it is in standby mode and the screen displays the water temperature in the water jacket, the time and the
time zone (if it is enabled). To activate the control panel press the F1
(
3
) key once. To disable it hold the same key pressed for about 1
second.

The device status is indicated in the graphic display screen ( 2 ) in the form of text and images. It also includes information on the operation of
individual system components, temperature sensors and it allows changing parameters.
Switching between the different displays is done by the TOGGLE (
7
) key. When you are in a display that allows any parameter change you
must press the CONFIRM (
6
) key. The parameter field will start flashing and you can now change the value by pressing the (
4
) or (
5
)
keys. If any display has more than one parameter fields, move between them with the TOGGLE (
7
) key and by pressing the CONFIRM (
6
)
key register that change.
!
If you do not register the altered parameter within 10 seconds, it will be ignored by the regulator. The field will stop flashing and the
parameter will revert to its previous value.
