2 UNIT DESCRIPTION
2.1 General
The Rotex RKOMB*AAV1 wall-mounted gas boiler is a closed unit. The unit is intended
to provide heat to the water of a CH-installation and the domestic hot water installation.
The air supply and combustion gas outlet can be connected to the unit by means of two
separate pipes. A concentric connection can be supplied upon demand. The unit was
tested in combination with the combi feed through, but the unit may also be connected
to combi feed throughs which meet the universal test standards for combi feed
throughs.
The unit can be connected to a assembly bracket if required, a frame with top
connection, and various installation sets. The are provided separately.
The Rotex RKOMB*AAV1 wall-mounted gas boilers have the CE quality mark, electrical
protection class IP44.
It is possible to use the unit solely for warm water, or solely for heating. The system
which is not in use, does not need to be connected (see par. 7.2).
The unit is delivered for natural gas (G20) as a standard. On request, the unit can also
be provided for propane (G31).
2.2 Functioning
The Rotex RKOMB*AAV1 wall-mounted gas boiler is a modulating high efficiency
boiler. This means that the power is modulated to suit the required heat demand. In the
aluminum heat exchanger two separate copper circuits are integrated.
The separate circuits for CH and warm water allows the heating and warm water supply
to function independently. The hot water supply takes precedence over the heating.
Both cannot work at the same time.
The unit is fitted with an electronic boiler controller machine, which operates the fan at
every heat requirement of the heating or the warm water supply, opens the gas valve,
ignites the boiler controller, and continuously monitors and regulates the flame,
depending on the requested power.
2.3 Operating modes
The operating mode of the unit is indicated by means of a code on the service display
of the operating panel.
-
Off
The unit is not in operation, but is connected to the electricity supply. No response is
given to requests for domestic hot water of CH water. The unit frost protection is active.
This means that the pump will start running and the exchanger will be heated up if the
temperature of the water in the system drops too far.
If the frost protection intervenes, the code
7
will be displayed (heating up exchanger).
The pressure in the CH installation can also be read from the temperature display in
this operating mode (in Bar).
Standby
The LED at the key is lit and possibly one of the LEDs of the tap comfort function.
The unit is ready to respond to a request for CH or tap water.
