My son in Boston has a new SlantFin Lynx NG boiler with a seperate Combi-cat hot water unit for DHW and radiant baseboard heat. He wants to switch from a non-programmable thermostat to a programmable. Honeywell makes a hydronic unit (TL8100A) that seems to be suitable. Is this a DYI product or must an electrician/plumber install it as it says it must face the unit for some reason and can be tied into various line voltages (see below)?
Honeywell’s TL8100 Hydronic Thermostat offers the energy savings of a programmable control for a wide variety of applications. With the TL8100 there’s no need to carry multiple thermostats for different applications. It can be used to control 2-way
zone valves, 3-way zone valves or circulator pumps in both line volt and low volt applications.It also offers special protection modes to prevent system seizures and to reduce callbacks.
Easy to install, the TL8100 is exactly what you need to provide your customers with cost-efficient programmable control of hydronic heating systems…and much more!
