A1 – RVA 43. 222 EQUITHERM REGULATOR
is a boiler and heating circuit regulator for a double stage burner incl. the possibility to prepare HWS
(hot supply water), with a pump heating circuit (without the mixing valve).
Other regulator characteristics are as follows:
•
the regulation of heating circuit with a circulating
pump (without the mixing valve)
or:
•
connection in a cascade (up to 4 boilers)*
A2 - RVA 46. 531 + RVA 43.222 EQUITHERM REGULATOR
is a set of boiler and heating circuit regulators for a double stage burner incl. the possibility to prepare
HWS (hot supply water), with a mixing valve in the heating circuit.
Other regulator characteristics are as follows:
•
Suitable first of all for connection in a cascade
(up to 4 boilers) *
A3 - RVA 63.280 EQUITHERM REGULATOR
is a boiler and heating circuit regulator for a double stage burner incl. the possibility to prepare HWS (hot
supply water), with two sensors and two mixing valves.
Other regulator characteristics are as follows:
•
the heating circuits can be set as independent
(two separate heating circuits) or as dependent
(floor heating in combination with radiators)
•
a separate time schedule programmed for HWS
(hot supply water) preparation
A4 - RVA 33. 121 EQUITHERM REGULATOR
is a boiler and heating circuit regulator for a single stage burner incl. the possibility to prepare HWS (hot
supply water), with a pump heating circuit (without the mixing valve).
Other regulator characteristics are as follows:
•
a separate time schedule programmed for HWS
(hot supply water) preparation
•
no other RVA regulators can be connected
* Note:
When connecting in a cascade each of the boilers must be equipped with RVA 43.222 regulator and
at least one of the boilers also with RVA 46.531 regulator (the number of RVA 46.531 regulators must
conform to the number of controlled heating circuits).
The regulator is enclosed according to the purchase incl. a separate operation manual. As a standard
the regulators are delivered together with QAZ 21, a submersible sensor for heating water
temperature.
