Hi
I have a Frost stat in outside boiler house for OFCH system
Noticed this evening this browning on top of the frost stat as per attached pics
The boiler house can be bit damp and prone to condensation so not sure if that browning on the frost stat is due to that
Is the frost stat kaput - has something blown on it or burned on it hence the browning and what could have happened. Its only installed a few years
The heating system is working (using it for heating the water)
Any thoughts?
Thanks
