I'll Fix It, Honey.

I've been working at a house where the husband is a mathematician/engineer. He was always the one that did the plumbing and electrical repairs in the house. He even did the work to repair any heating system problems. As he got older, fewer things got fixed. Slowly, the Honeywell zone valves stopped working and eventually, there was no heat in the house. The husband is now in a memory care facility and his wife has decided that she wants heat, so she called they only person - still alive - that worked on their system in the past - me.

I've replaced all the zone valves only to find out that none of the thermostats communicate with the controls in the boiler room. I suspect rats chewing through the wiring as they had a longtime vermin problem and I've replaced the old thermostats with Honeywell RedLINK wireless units.

All the old thermostats still work as does the transformer relay. They are so beautiful and I can't bring myself to throw any of them away.
