I bought Thermguard to prevent my my pipes from freezing again. Can I install the unit in my boiler room instead of on the thermostat? I would think that it would work on the other end just the same, is there something special that needs to be done?

Kevin C said:John,
I did exactly that and it works! Thank you for the great product and equally great service.

Hi Kevin,
Just find where the thermostat wires come into the boiler room, should be white and red. Connect ThermGuard across those wires. Connecting across the zone valve is not the correct thing to do. ThermGuard needs the thermostat wires. You can email me or call Bear Mountain Design (four zero six) 587-2478. I'd be glad to help.
Cheers,
John

Hi John
Honeywell V4044 and other Zone Valves connect direct to a Thermostat like the diagram below.
If you know something different please tell us?
Kevin C said:John,
The ThermGuard is set for 30 min intervals and 5 minute duration. Is this in your opinion the optimal time frame? I would prefer to have it come on every hour for 5 minutes. Would this setting still prevent the pipes from freezing?
Thanks,
Kevin

That's good to know. I set it for 2 hrs for 5 min The less oil I burn, the happier I am.
FordMastertech said:I got my ThermGuard rigged up over the past weekend. I mounted it to a small electronics box that has a 4PDT relay in it to turn on all 3 of my heating zones at the same time. I was able to grab 24 volts AC off the Taco zone controller to power the system. The last pole on the relay, Normally Closed, is used for the cold start boiler and it will run normally when the ThermGuard is not not cycling the circulators and there is a call for heat or indirect hot water. When the ThermGuard cycles the circulators the boiler will not fire unless the switch on the box is turned on and then the boiler will fire normally just like a call for heat or hot water. I have it off and just use the ThermGuard to circulate the water in the system every 2 hours for 5 minutes when the outside temps drop. There is a wall mounted thermostat to turn the system on when the concrete wall temps drop below 50 °F, it's got to get into the low to middle teens for the wall to get to 50 °F. The water flowing will keep the pipes from freezing and it wastes no heating oil by keeping the boiler off. The down side to my setup, when the switch is off and there is a heating/hot water call the boiler will not fire until the ThermGuard gets done with it's circulator cycle. I don't use the boiler much for heat so it will not be a problem for me and it's only for 5 minutes anyways. I will probably keep the switch in the off position until the outside temps get below the -10 °F.
The battery under the thermostat is my MT Vernon AE's 12 volt back up battery.

John,
That is an awesome setup! I have two zones and I would like to setup something like you have displayed in the picture. Can you give a material list and a brief description of the setup of the relay?
Thanks John for the schematic and thanks Ford for the pics of your setup. How is the cold start achieved? I would rather burn no oil and just circulate the pumps every two hours.bridgerman said:Kevin C said:FordMastertech said:I got my ThermGuard rigged up over the past weekend.

The photos above are from FordMasterTech, not Bear Mountain Design. He deserves the credit there! Here is a schematic with suggestions for the components. There may be a less expensive relay for two poles. I have listed a 4 pole.
Kevin C said:To be on the cautious side I will have ThermGuard turn the boiler on as well.
I guess my questions is, can't I just run a set of wires from Thermguard to both thermostat wires to have it control both zones or do I need the relay and transformer as described in your diagram?
