Honeywell Hydronic Heating Thermostat AQ1000TN2 AQ2000 Series
Honeywell AQ1000TN2 non-programmable communicating thermostat for use with Honeywell AQ2000 Series hydronic zoning systems. This thermostat is designed for hydronic heating applications and communicates with an AQ2000 series zoning module using a two-wire, polarity-insensitive connection. It can display indoor, outdoor, and floor temperatures when used with compatible accessories. Honeywell/Resideo has discontinued this model, making it desirable as a replacement for existing AQ2000 installations.
