The appliance can also be connected without the wall mounting frame using the robo kit. The Intergas Compact HRE SB wall mounted gas fired boiler carries the CE rating and IP20 electrical protection.

4 OPERATION 4.1 General The Intergas Compact HRE SB wall mounted, gas fired system boiler is a modulating high efficiency boiler. This means that the power is adjusted in line with the desired heat requirement. The appliance is equipped with an electronic boiler controller which, each time heat is requested from the heating supply, starts the fan, opens the gas valve, ignites the burner and continuously monitors and controls the flame, depending on the requested output.
The boiler controller is equipped with an interface for a PC, which can be connected by means of a special cable and associated Intergas Diagnostic Software (IDS). This facility allows the behaviour of the boiler controller, the appliance and the heating installation to be monitored over a longer period.
If the appliance is out of operation ( on the service display) the appliance ’s internal frost protection is still active. However, this means there will be no response to a request for heat from an (external) frost thermostat. Intergas Heating Ltd...
