6/8 will allow the burner to fire. For the ignition sequence to start Live power must be connected to terminal 1 the
Danfoss control box. This is achieved by connecting contact 6 on Relay (2) through either of the operating
thermostats to terminal 1 on Relay (1) and to terminal 1 in control box via connector block L3.
When cooking the oven thermostat priority switch must be on (on cooking). These contacts operate Relay (1)
which isolates the BOILER thermostat. The connection is completed through the temperature controlled switch
connections of the COOKER THERMOSTAT.
Id the boiler water temperature during the operation of the appliance under the control of the cooker thermostat
rises too high then the pump overrun thermostat will operate. This remove the power from Relay (2) which cuts
out the supply of power to the burner but still keeps the circulating pump operating.
4.3.2. Heating
Since the cooker thermostat has priority, the appliance can be controlled by the boiler thermostat only when the
oven thermostat priority switch is off (on heating). The sequence of events is exactly the same as for cooking
except the circuit is completed now by the temperature controlled switch connections in the BOILER thermostat.
4.3.3 Pump Overrun Thermostat
When the time clock/programmer switches off at the end of the cooking and or heating period the circulating
pump is switched off as well as the cooker. If in the period of time after the pump has gone off the water
temperature in the boiler should rise too much then the pump overrun thermostat will operate and switch on the
pump (but not the burner).
