Tekmar 401 tN2 House Control, Boiler, DHW and Setpoint, Four Zone Pumps.
This Tekmar 401 tekmarNet® 2 House Control is designed to operate all of the mechanical equipment in a residential hydronic heating system, coordinating their operation through network communication. It can be used in applications ranging from a single zone of baseboard with an on/off boiler, to multiple radiant floor zones with a modulating/condensing boiler. This control regulates one space heating water temperature through Outdoor Temperature Reset and Indoor Temperature Feedback. It is capable of controlling a single on/off, two stage, or modulating boiler, Domestic Hot Water, setpoint loads, 4 on-board zone pumps, and can expand up to 24 zones in total.
Product Features:
- Outdoor temperature reset, indoor temperature feedback
- Setpoint operation, automatic boiler differential
- For use with tekmarNet® 2 thermostats only, tN4 expansion terminals
- Only requires 2 Wires Per Zone, Four 115 V (ac) powered zone outputs
