TRADITIONAL SYSTEM – RADIATORS HIGH TEMP. UNDERFLOOR HEATING SYSTEM
With Parameter nr.20=11, Par. nr. 21 and Par.22 we define the maximum and minimum limit of the Heating Set Point (SP)
The Rec07 has not the dry contact, typical of the Ambient Thermostat, which is necessary to energize the zone valve - VDZ (230 vac). Thus, if we want
the Rec07 to energize its Zone Valve, it is necessary to use Kit Cod.1103039. The kit includes an electronic PCB “BE08” connected to the boiler electronic
PCB (AE02). When the Rec07 makes a heating call, it is closed the BE08 dry contact which energizes the Zone Valve. Once opened, this Zone Valve
closes its limit switch contact (FC) connected in parallel to other ones on the boiler Ambient Thermostat clamp. In this way, the boiler starts heating only
if at least a zone makes a heating call.
If the Rec07 has not to manage a zone, it is not necessary to have a kit Cod.1103039 and it has to be set modifying its 3 day temperature, the night tem-
perature at 5 °C and the parameter
“ROOM – INFL”=20, in order to avoid any heating call. The different Ambient Thermostats (TA) energize their respective Zone Valves through the limit
switch contacts (FC) placed in parallel on the boiler Ambient Thermostat contact.
When we have a heating call from the limit switch contacts (FC) of the Zone Valves controlled by the Rec07 or the Ambient Thermostats, the boiler starts
working with a heating set point (SP) defined with the heating encoder (20÷80°C = Par.22÷Par.21).
