With Parameter nr.20=11, Parameter nr.44=1, Par.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 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 INFLAMB=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 system works
according to the thermoregulation of the electronic PCB embedded in the boiler (AE02), thanks to Parameter nr.44=1 and with the climatic curve defined
with Parameter nr.45: 20 (default) for systems with high temperature, 10 for systems with low temperature, but the value can be modified according to the
system characteristics. It is suggested to keep the Parameter nr.3 = 5 and use the Parameter nr.65 to define the reactivity value of the external probe. If
the house is new and well insulated, the Parameter nr.65 can be set at 20÷25 as the internal temperature varies more slowly than the external one. If the
house is scarcely insulated, it is advisable to set values between 10÷15. Rotating the ENCODER for Central Heating settings it is possible to optimize the
curve with a translation of ±5°C on the required ambient temperature used for the thermoregulation calculation.
