Honeywell offers a complete range of relays, contactors and transformers for all your residential
and commercial HVAC applications. All Honeywell products are designed to exceed safety and
industry life cycle standards. In order to meet these criteria, a statistically significant sample of
Honeywell products are tested to failure and to our stringent qualification requirements. This testing
methodology enables Honeywell to verify that these products will exceed industry standards.

Relays
Honeywell’s switching relays are available in multiple configurations for various applications. For
whatever you need — general purpose relays or electric heat relays — Honeywell has you covered.
• General Purpose and Heavy-Duty Switching Relays — R4222, R8222, R4228 and R8228 for use in
refrigeration and air-conditioning equipment, appliances and vending machines
• Time Delay Relay — ST82 combines the R8222 or R8228 relay for use in compressor-run air
conditioning and heat pump systems; this product features an electronic timer that delays blower shut
off after the compressor has shut off.
• Fully Enclosed Line and Low-Voltage Fan Relays — R4225 and R8225 for control of line voltage fan
motors and auxiliary circuits.
