Features

• Type of EU certification (CE PIN code 0694BR1154) in accordance with Directive 90/396 on gas appliances and the following amendment to Directive 93/68;

• In accordance with EN 298 (European standard for automatic programming and flame control systems for gas burners);

• Flame control based on the rectifying properties of the flame (ionization);

• Two independent safety contacts in series at the outlet of the gas valve (models with manual reset);

• Service life of electrical equipment at max. declared load > 250,000 operations;

• Built-in fully solid-state ignition device with high efficiency;

• Auxiliary contact for low-power ignition or control of the main gas valve in intermittent power control systems (this contact is not isolated from the main supply voltage by reinforced insulation, therefore the relay contact is not suitable for controlling SELV circuits

Application

• Steam convectors;

• Heating boilers;

• Warm air generators;

• Radiator tubular heaters;

• Water heaters and other gas installations with an atmospheric burner.
