Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

If only 1 zone is acting up then you could have a faulty thermostat. It sounds like you have a programmable thermostat. I'd try setting the thermostat to HOLD and the desired temp then see if the problem is resolved. If it does then I'd replace the thermostat.

i dont have programable thermostat i had my tenant set it on 80 before he went to bed still woke up it was 60 in the apartment i kept checking heat pipe were hot up to 230-300 then i went to bed this has been happening for awhile

i have a computer controling the burner it shuts down the hot water at 1030 to 430 to save oil
HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

If the water temp was 230 to 300 then you have a serious control problem. How are you measuring those temps? Are you sure your clock settings on the Logamatic are accurate? What model Logamatic do you have?

In any event if only 1 zone is affected then the only explanation is either a thermostat or zone control issue. What do you have for zone control? zone valves? what brand? or a pump for each zone? if so what do you have for a relay controlling the pumps?

no i meant i checked the pipes at 2am to 3am they were hot
HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

Ok, that makes more sense. I still need answers to my last questions. If the other zones are OK then there's a problem with the 3rd floor zone control. Since that floor has heat other times of the day the only culprit is what's controlling the flow of heat to that floor. While there is a remote chance there's not enough radiation (baseboard?) on that floor and the time you mention is the coldest time of the day, that one isn't very high on my list

each zone has its own pump there are 3 zones 1st floor 2nd floor and hot water computer has a night and day setting it shuts hot water down around 11 pm to 5 am bot answers call for heat or at least it should the living rm/kitchen area has a convector
HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

What controls the pumps? are they connected to the Logamatic or a relay?

What model Logamatic?

Ask Your Own HVAC Question
HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

As far as I know the Logamatic only has provisions for 1 pump. If you have 3 then they must (or should) be connected to a relay

HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

If you start at the pump (for the 3rd floor) and follow the wiring it should connect to a relay. I need to know what brand and model that relay is. I also need a picture of the wiring connections in the relay. You can post a pic here by clicking on ADD FILES next to the SEND button

there is a relay logamatic is for a G-115 relay is ARGO
HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

Ok, I need to see the wiring connections inside the Argo.

Ask Your Own HVAC Question
HVAC Technician: Rick, HVAC Supervisor replied 2 years ago

If you can't provide a picture of the relay wiring I'll give you my assessment based on what you've told me so far and what I've seen all to often in the past. I suspect the 3rd floor zone is not calling the burner in when there is a call for heat. So all that happens is that the thermostat turns on the pump and the pump circulates whatever temp water is in the boiler. If none of the other zones are calling then that could make the boiler water not very hot at all. Too often I've seen relays mis-wired in this fashion. It's also possible that there's not enough radiation (baseboard etc) in the 3rd floor zone to keep the space warm during the coldest times of the day and the mis-wiring would make that worse. There's no way I can tell from just your inventory of the baseboard if it is adequate. A detailed heat loss analysis would be required to make that determination.
