LEAVE THIS MANUAL AS A REFERENCE GUIDE FOR THE USER
WARNINGS
The following instructions must be read and understood before installing, commissioning and
maintaining the regulator.
The safety symbol is used in this manual to draw attention to the relative safety instructions. The
meaning of this symbol is as follows:
CAUTION!
YOUR SAFETY IS INVOLVED. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY
RESULT IN INJURY.
- The digital regulator must be installed by a licensed installer in accordance with national regulations and/or
relevant local requirements.
- If the digital regulator is not installed, commissioned and maintained correctly in accordance with the instructions
in this manual, then it might not work properly and may endanger the user.
CAUTION: Risk of electric shock. The rear panel is live. Cut off the electric supply
before carrying out any work. Failure to follow these instructions may result in
personal injury or damage to property.
- Minimum working temperature of the
solid fuel generator (TSG, working temperature range: 20–85°C): °C (factory setting: 55°C).
It is good practice to compile the two blank fields to facilitate any system checks to be performed.
When the solid fuel generator is equipped with an anti-condensation valve, it is good practice to set the minimum
working temperature of the solid fuel generator (TSG, settable in the regulator menu) to a value at least 2°C higher than
the anti-condensation valve setting.
- Anti-condensation valve setting:
°C
