SOURCE: I want to adjust the

To enter the adjustment mode, press the UP, DOWN, and I buttons simultaneously for three seconds. Press the I button until the feature requiring adjustment is displayed:
• HL —High Limit.
• LL— Low Limit.
• Ldf —Low Limit differential.
Then press the UP and/or DOWN buttons to move the set point to
the desired value. After 60 seconds without any button inputs, the
control will automatically return to the READ mode.

(copied from honeywell's instructions)

to clarify the differential is cut in minus the cut out.
Hope i can be some help to you.

I have a hot water boiler with 3 zone valves and 2 circulation pumps. I see no relays wired to pumps. Pumps run constantly


Sounds like a lot of unknowns from your article. Here are some basic checks

- if they are the honeywell zone valves and you try to open them and get resistance than 9/10 times the t-stat is not calling for heat and the valve should be closed
-if stat is calling and wants heat zone valve lever should be free of resistance when moving it
- 15-20 psi is a little high but could be normal based on the size of your place and the temperature you are reading these pressures at
-with the pumps always running seems to me that the pumps are hard wired to a constant electrical source, if you want optimal control install a taco zone controller

I have a two zone water baseboard system... I installed a new zone valve to the upper zone which was not calling for heat.. the only heat it got was when the lower zone was circulating... Now the upper...


Good clues to work with--
Let's review how you wired up the Zone Valves, in relation to the Boiler Control panel...

You say the upper zone does NOT SHUT DOWN--
Does that mean it is OPEN ALL THE TIME?-- (even when the circulating pump is OFF? )
That sounds like the thermostat is not even in the circuit, then.

Have you been able to cycle each of the valves thru their cycles-- Open- and then closed?
-- It almost sounds like you have an interconnection between the two valves-- is this possible?

Each Thermostat has to control its valve only...
and most systems do this thru a control panel at the boiler--
So-- How is your control panel connected to the 2 thermostats, and how are the 2 zone valves connected to the Control board?

Are you following a wiring schematic for hooking the valves and thermostats to the control board?
There should be a schematic with the new valve you must installed, right?
did you wire it like the instructions showed?

Make a few more tests, and get back with us--

Solid fuel stove linked to oilsystem with two zone


Put a temperature operated control (aquastat) on the piping of the wood stove so that if it is on, it will interupt the circuit wired to the oil burner at the X&X terminals of the boiler control.As the wood stove cools off, it will close the connection allowing the oil system to fire.

I have a red and a white wire but the heater wont


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!!

Blinking red light no heat


It sounds like you are actually in lock out. Recycle is when during a call for heat, the flame goes out, the unit will try to restart itself. Hope this helps

One zone not working; another is partly working


i would check my water pressure on boiler sounds like lack of pressure or air in system they can be related. if you have bleeder on baseboard try to bleed.
