Boiler Controls and Thermostats for AERCO (Watts) boilers
A boiler is only as smart as the controls wired to it. A thermostat in the wrong place, a zone valve never wired into the boiler's logic, or a condensing boiler left on fixed high-temperature settings all waste heat and wear equipment. ROMA's control work covers replacing and installing thermostats, wiring and configuring zone controls, and setting up the modulating and weather-responsive controls a condensing system needs to behave correctly.
Control work is electrical, and it must respect the boiler manufacturer's wiring diagrams, safety sequences and the applicable gas and electrical codes. Whether the job is a single thermostat upgrade, adding a second zone or reconfiguring a control curve after a retrofit, it ends with the operating sequence tested and explained, not just wires connected.

Frequently asked questions
Which smart thermostat works with my boiler?
Compatibility depends on the boiler's control voltage and your zoning. ROMA checks the actual wiring and boiler logic before recommending a thermostat, so the answer is specific to your system.
My thermostat is in a cold hallway. Can anything be done?
Location matters: a poorly placed thermostat makes the whole house feel wrong. Relocation or zone-level sensing may be options; the assessment will tell you what your system supports.
Will a new thermostat fix my cold rooms?
Only if the cause is control-related. If some rooms stay cold while others overheat, the cause is more likely in zoning or balancing, which is why the visit verifies the cause before selling you a thermostat.
