DESCRIPTION OF THE APPLIANCE General The Intergas Rapid HR wall mounted, gas fired boiler is a closed appliance. The appliance is intended to deliver heat to the water in a CH system and the DHW installation. The air supply and combustion gas flue can be connected to the appliance by means of two separate pipes.
Operating conditions A code on the service display of the operating panel indicates the appliance’s operating mode. - Off The appliance is out of operation but is supplied with electrical power. No response occurs to calls for DHW or CH. The appliance frost protection is active.

In the case of an external sensor the desired CH supply temperature is determined by the heating line programmed in the burner manager. For the latter two, however, the maximum is the temperature set on the display. The CH operation the requested CH supply temperature is indicated on the operating panel.
Clock function The boiler is equipped with a digital clock and offers the possibility to program 4 points in time to switch from CH off or CH on. During the “clock active” periods the boiler will respond on CH demands from the room thermostat.
2.6.1 Frost protection To prevent freezing of the appliance it is equipped with appliance • frost protection. If the heat exchanger temperature falls to low, the burner switches on and the pump runs until the heat exchanger temperature is sufficient. When the appliance frost protection is actuated code 7 ‘...
