Honeywell's TL8100 Hydronic Thermostat offers the energy savings of a programmable control for a wide variety of 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.
The TL8100 works in the following Hydronic applications:
. Line volt circulators
. 24 volt circulator relays
. 24 volt zone valves
. 120 volt zone valves
Not only is the TL8100 great for valve and pump control, it also does much more!
. Electric heating up to 1200W@ 240V max.
. Millivolt systems (e.g., gas fireplaces)
. Gas, oil or electric systems
. Hot air system with no fan control
