Tekmar Controls 401 Pump
The Tekmar 401 House Control is a versatile 24Vac solution designed for integrated hydronic systems requiring precise management of up to four zone pumps, a single boiler, and domestic hot water (DHW) production. Engineered with tN2 communication technology, this control simplifies wiring by using two wires for both power and communication between compatible thermostats and the main module. It functions effectively as a centralized hub for multi-zone hydronic radiant heating systems, offering programmable logic for boiler enable, setpoint generation, and priority DHW operation. By utilizing an indoor sensor or outdoor reset via tN4 system integration, the 401 optimizes boiler plant efficiency and prevents short-cycling. This controller is essential for contractors seeking a reliable 24V pump relay replacement that provides advanced diagnostic capabilities and centralized wiring for complex residential or light commercial mechanical rooms.
- Universal HVAC Integration: Manages up to four heat zones and one DHW tank, reducing the need for multiple independent relay boxes.
- Advanced tN2 Communication: Reduces installation time and potential wiring errors by using a simple two-wire non-polarized connection for thermostats.
- DHW Priority Logic: Automatically manages heat distribution to ensure domestic hot water demands are met without compromising system pressure or temperature balance.
- LED Functional Diagnostics: Provides immediate visual feedback on system status, pump activation, and communication health for faster troubleshooting on-site.
Common Technical Questions
How many zone pumps can be connected to the Tekmar 401?
The unit is designed to control up to four 120Vac zone pumps directly when used in conjunction with the proper power supply, while also providing a dry contact for boiler activation.
Is the Tekmar 401 compatible with tN4 thermostats?
While the 401 primarily utilizes tN2 technology for zone communication, it can be integrated into larger tN4 systems to receive outdoor temperature data and system-wide setpoint requirements.
Can this control handle Domestic Hot Water priority?
Yes, the 401 includes dedicated logic to prioritize DHW production, ensuring the boiler focuses energy on the hot water tank before resuming space heating cycles.
