Get great deals on honeywell boiler furnaces central heating systems. They are used in coordination with circulator pumps and programmable thermostats to control zoning in a hydronic heating system. Take this time at home and knock out some home improvement tasks. We are the leading suppliers of domestic heating and combustion controls in the uk with products that include time temperature gas and water controls.

110 f to 220 f high limit. Provide multizone control by using a separate circulator and r845 relay for each zone include diaphragm powerhead and micro switch assembly that respond to temperature changes in boiler water low limit. Switching relays are used to control the flow of water in a heating system by monitoring temperatures and adjusting boiler water temperature to match the demand. Subbase and amplifier are required to complete the system.
