Laars Heating Systems RE2077700 Relay
The Laars Heating Systems RE2077700 Relay is a specialized 24V 15A 6/600S Time Delay Relay engineered for precision sequence control in commercial and residential hydronic systems. Built for heavy-duty cycling, this SPDT HVAC relay manages electrical surges and prevents damaging short-cycling by implementing a customizable delay range from 6 to 600 seconds. This OEM Laars replacement part is essential for protecting inducer motors and ignition modules by ensures that system components engage in the correct sequence, reducing power spikes during high-fire transitions.
As a veteran-grade boiler control relay, the RE2077700 is designed to optimize energy consumption by minimizing unnecessary startups and maintaining a smooth operational heartbeat. It handles a 15A current rating at 24VAC, making it compatible with a wide range of Laars Teledyne units and furnace systems. Field technicians rely on this time delay sequencer for its robust construction and ease of integration into existing low-voltage control circuits, ensuring long-term reliability in demanding thermal environments.
Key Benefits:- Precise Sequence Control: Adjustable 6 to 600-second delay prevent simultaneous component extraction and power surges.
- Anti-Short Cycle Protection: Extends the service life of burners and inducer motors by eliminating rapid on/off cycles.
- High Amperage Rating: Reliable 15A switching capacity at 24V for demanding HVACR applications.
- Optimized Efficiency: Reduces fuel waste and electrical wear by regulating system startups based on actual load demand.
How do I adjust the timing on the RE2077700?
The relay features an adjustable dial or jumper setting (depending on the specific series revision) that allows for a delay range between 6 seconds and 10 minutes to match your specific system’s purge or ignition requirements.
What happens if the relay fails to close?
Failure to close typically results in the system being stuck in standby mode or "Call for Heat" without the blower or gas valve engaging. Verify 24V input at the TH terminal and check for continuity across the contacts once the delay period has elapsed.
Can this relay replace a standard 24V switching relay?
While it operates on 24V, it is specifically a time-delay model. It should only be used where a timed sequence is required for safety or manufacturer-specific operational logic.
