Tekmar Controls 654 Control
The Tekmar Controls 654 Control is a sophisticated 24Vac snow melting control designed for precise regulation of either electric snow melting systems or hydronic snow melting equipment. This controller utilizes automatic snow detection via a 090 or 094 sensor to initiate the system only when precipitation is present at freezing temperatures, preventing unnecessary energy consumption. It features an integrated slab temperature sensor input to maintain precise slab temperatures and provide high-limit protection, ensuring the integrity of the concrete or asphalt. The 654 is compatible with Pulse Width Modulation (PWM) for hydronic mixing valves and offers flexible boiler demand signaling. For contractors managing commercial snow melt systems, the 654 provides a reliable BAS integration point through its 0-10V input, allowing for remote enabling or slab temperature setpoint adjustments in complex HVACR environments.
Key Benefits:
- Compatible with both automatic snow sensors and manual override switches for versatile system control.
- Supports tandem snow melting applications to coordinate multiple zones effectively.
- Features a dedicated slab outdoor design temperature setting to optimize reaction times during heavy snowfall.
- Includes econo-melt functionality to reduce energy costs during periods of lower priority melting.
- Provides warm weather shut down (WWSD) and cold weather cut out (CWCO) to protect equipment and improve efficiency.
Common Questions:
Does the Tekmar 654 support 0-10V DC signals for modulating equipment?
Yes, the 654 can accept a 0-10V (dc) input to adjust the slab target temperature or to manually enable the system from an external building automation system.
Can this control manage both hydronic and electric systems?
Yes, the Tekmar 654 is engineered with internal relays and logic capable of controlling hydronic heating pumps and valves or triggering electric heating contactors.
What happens if the slab sensor fails?
The control includes sensor monitoring; if a fault is detected, the system can be configured to default to a manual run time or shut down to prevent overheating the slab.
