Roth 1050 Controller to Honeywell AQ25244B

Boiler Controllers

Boiler controllers can be very intimidating, especially if you do not deal with the same controller all the time. To make matters worse we had a burnt out Roth 1050 controller (Tekmar) that provided zero information on the installers custom settings. The Roth #1050 was manufactured by Tekmar, Tekmar was a leading manufacture and provider of boiler controllers. That was until the industry they provided controllers to caught up to their technology and started to produce their own controllers at a much more reasonable cost.

Burnt Controller

After removing the circuit board from the housing you can see under the blue capacitor a burnt spot, now in some cases you can have these boards repaired, unfortunately this board was beyond repair. And the very sad part is these boards are becoming scarce and very expensive. Our solution was to move to a Honeywell AQ25244B controller with a AQ25744B expansion panel. Honeywell is less expensive and readily available.

Honeywell AQ25244B controller

Not only would the Honeywell controller replace the the boilers Roth 1050 controller it would also replace the 2 Taco zone controllers that where on the system as well.

We installed the Honeywell AQ25244B controller in a more accessible area for the home owner as well as for the service technician. Because the new controller did the task of 3 components all the wiring had to come back to this location.

Boiler System Back Up And Running

Once the new Honeywell controller is installed we still have a few hours left configuring the system and to make sure the system is working correctly.
