Performance Specifications

• Operation is by Class A software and Type 2 action. Version 3

• The mains supply to the electronic circuit is protected by a time delay fuse.

• Flame failure input: 230Vac nominal, 200Vac to 253Vac actual, 50Hz. Presence of voltage indicates flame failure.

• The burner reset output is either volt free or Live/Neutral (selected by a plug-in jumper)

• Remote volt-free switch outputs will be 24Vdc/5mA

• The built-in room temperature sensor has a measuring range of 0º C to 30º C with a resolution of 0.2º C.

• Temperature sensor readings can be offset to allow for errors due to sensor tolerances and location. NB Frost protec
