Tekmar Controls 304P Relay Panel
The Tekmar Controls 304P Relay Panel is a professional-grade 4-zone switching relay engineered to manage up to four low-voltage thermostats and four 120V circulating pumps in hydronic heating applications. Built for technicians who demand reliability in zoned radiant floor or baseboard systems, this hydronic zone control utilizes a microprocessor-based design to coordinate calls for heat with precision. The 304P switching relay features RoomResponse technology, which provides a 0-10V (dc) or 4-20mA signal to modulating-condensing boilers, optimizing water temperatures based on real-time zone demand to prevent short-cycling and improve efficiency. Zone 1 is field-configurable for DHW priority, allowing seamless integration of an indirect domestic hot water tank. The unit is fully expandable for unlimited zones using additional relay panels. For long-term protection, it includes integrated pump exercising to prevent seasonal seizing and post-purge functionality to extract residual heat from the heat exchanger, maximizing system performance and contractor profitability.
Key Benefits- Universal Compatibility: Works with all standard 24VAC thermostats and 115VAC circulator pumps, making it a versatile boiler relay panel for retrofit or new installs.
- Optimized Efficiency: RoomResponse signal automatically adjusts boiler firing rates based on thermostat feedback without the need for an outdoor sensor.
- Flexible Zoning: Supports priority override and can be expanded for large-scale residential or light commercial projects using simple wiring jumpers.
- Diagnostic LEDs: External indicators provide instant status updates for power, zone calls, and DHW priority for faster troubleshooting.
- Robust Protection: Equipped with internal fuses to protect the 40VA transformer and pump outputs, with two spare fuses included inside the enclosure.
How many pumps can the Tekmar 304P handle?
This panel controls up to four individual circulator pumps (5A, 1/3 HP each) and can be expanded to manage more by linking additional units.
Does this relay panel support indirect water heaters?
Yes, Zone 1 features a DHW end switch and optional priority logic specifically designed to support domestic hot water priority over space heating zones.
Can I use a smart thermostat with the 304P?
The 304P is compatible with all low-voltage thermostats; however, power-stealing thermostats may require a 4.7k ohm resistor or a common wire to ensure the internal 24V transformer is not overloaded.
