Tekmar 256 Outdoor boiler reset Question

Hello everyone,

I was hoping someone could help answer a question for me, does the Tekmar 256 maintain a minimum boiler temp or does it cold fire the boiler, the manual doesn't say much.

Thank you in advance for any help.

    Depends, terminal #7 &#9 when close by a jumper or boiler demand switch will allow the boiler to fire. The outdoor air temp will determine how hot the boiler water gets.
