The heating system uses hot water, the boiler uses oil. I have 4 zones.
Problem 1. On one zone, which happens to be the 2nd flr, the baseboards are cold even when the thermostat is set at 70. In the boiler room, there are 4 zone valves; the pipe on one of the zone valves is not as hot as all the other 3.
Problem 2. In the first floor, there are two zones with seven baseboards. Three of the baseboards used to work but now remain cold.
I would appreciate if you could tell me what are casing the problems.

You have a real good description of your thermostat-- I wonder why you suspect the thermostat to be causing your 'No Hot Water' problem?
First of all, I have to be sure I understand your real problem-- When you say you want to 'turn the Hot Water back on', (It is 'Not going') Do you mean you want a boiler (maybe in the basement?) -- or maybe a zone valve in a Hot Water, Baseboard heating system-- to be heating your house/ room/ apartment?
I would suppose, if you have the thermostat set higher than the room temperature, that it should be giving a 'call' to the boiler (or Baseboard Hot Water Heater..) to ignite a fire, and heat the waer, and then heat your room, or house.
So-- Could the problem be in the Device heating the Hot Water?
Please tell us more about your heating system-- what type of fuel, -- What happens when you lower the Thermostat, and then raise it-- What used to happen, and what does NOT now happen, etc.
Tell us more clues-- maybe we can help remotely like this-
There would be virtually no correlation between thermostats and CO. Anything that has happened would be purely coincidental. All the thermostats do is tell the heating to come on or off. If you have a CO problem then there is a major problem with heting plant. You need to find first the source of the co and then the reason why you are making co in great enough quanities to be a problem and how it is getting into the heated space.
My thought is... why did you change the t-stats in the first place??? was there an issue that caused the change and then to CO problem which was happening or going to happen anyway??
It sounds like you have at least 2 zones in your system. If this is a normal hot water boiler system with zone valves. When you have your thermostat call for heat it closes the 24 volt circuit that then energizes the motorized zone valve for that thermostat. In that motorized zone valve there is an end switch that will close and complete the circuit to the boiler. Zone valves when they start to clog up with mineralization will not allow the motor to go far enough to close the end switch, so then the boiler and circulating pump will not come on. If this is the case then you need to have the zone valve replaced. Also make sure your wires at the thermostat are connected correctly. One thing you could also check at the thermostat to make sure it works or not is to jumper the 2 wires and see if your system starts up or not. If the system starts up then the thermostat or its subbase is defective. Hope I was of help to you!! Good luck!!
ASSUMING THAT YOU HAVE HOT WATER SYSTEM,IT IS TIME TO THINK ABOUT REPLACING THE ZONE VALVE.IF YOU DISCONNECT THE ZONE VALVE,THAT AREA WILL NOT GET
ANY HEAT.IF YOU CAN GET THROUGH REST OF THE HEATING SEASON WITHOUT IT,TURN OFF THE POWER TO THE ENTIRE SYSTEM.THEN DISCONNECT THE POWER SUPPLY TO JUST THAT VALVE.BE CAREFUL TO PUT WIRE NUTS ON ANY EXPOSED BARE WIRES.YOU CAN THEN RESTORE POWER TO THE MAIN SYSTEM.
Since you have three on/off timing modes could there be an overlap in the times?
The wires in the unit might be crossed. (don't always assume the contractor who wired maintained the correct colors , I have a friend who blew out a heating pipe because when a replacement motor valve was installed it was never wired right and the plumber assumed the colors were correct so no overtemp shutoff created steam in PVC pipes, OPPS)
There fore maybe one is still coming on. Do you have more than one heating zone? IF so see below
I guess the main question is why manually turn it off? why not use the program.
I will assume your heat is know as forced hot water heating. My house is multizoned however when the zone calling for heat turns off (zone valve closes) I installed a bypass valve in the lowest zone in the house, and reduced the circulator low shut off temp to 130 F which means even though the heat isn't on my circulator will continue to run dumping this excess heat in the lowest part of house to rise through house. (the spring loaded water valve allows the heated water to flow into this zone )We do have two thermistats. And even though the lowest one is not calling for heat the radiators are hot when the excess is dumped into this zone. So investigate and see if your system might be similar. (multizone).
Investigate your wiring, reprogram, replace any battery backup.
Ger, do you get your hot water off the same boiler and it that working alright? How many zones and are they controled by zone valves (little boxes mounted on the pipes) or circulators (small pumps)?
Boiling water sounds can indicate hard water deposits in the boiler or that your aquastat is set too high allowing the water to heat up higher than it should. Check your boiler guage and let me know what temperature you are recording. Get back to me with the answers to my questions, we'll figure it out.
