SOURCE: replacing Honeywell heating progrmmer

yep the wires will hook up to the same designations, just write down what color was connected where. You will need to set the thermostat up for your particular situation...gas, electric, heat pump, ect. The installation maunel is very clear on this aspect so you should not have a problem.

SOURCE: how do i remove my st699 honeywell programmer from

Because there are no apparent screws to remove the front of this unit it can be very confusing if you have not done it before. Underneath and to the right hand side you will find a small notch in the plastic, it can be difficult to see when the unit is on the wall, using a small terminal screwdriver push upwards on the plastic tab which locks the front in place and with a slightly larger flat bladed screwdriver prise the front off bottom first then the two locking tabs at the top.
You will probably find that the back case is fastened to the wall with two screws.
Replacement is simply a matter of snapping the front back into the case.

Our heating and hot water keeps turning off


Sounds like a glitche in the thermostat. First, override the program & see if it does the same thing over the next few days.

Can you replace a danfoss TP9 with a honeywell ST699


I believe the TP9 is a programmable thermostat.

While it appears the ST699 is a timer that connects to a thermostat.

So yes, they both control 230Volt boiler-and-pump. But there are differences.
Google search each item and include .pdf in search parameter to find product manual for each, and then compare wiring differences.

If you go to your local home depot, and get a new thermostat, it will come with different diagrams for wiring in the instructions that are pretty easy to understand. I hope this helps.
