LENNOX 14B05 Corporation Heat Relay

Heat Relay

Heat Relays are used in heating and air conditioning. They detect changes in flow conditions (which can be caused by devices such as valves and static pressure metering devices) which signal the need for the application of energy for maintaining the desired temperature and humidification or dehumidification to a conditioned space. The heat relay opens and closes an electrical circuit to control the operation of either room temperature or boiler water heating equipment, such as gas valves, gas valve assemblies, electric water heater elements, solenoid valves, and air-handling unit auxiliary heat systems.

The Lennox Heat Relay is a tried and true method for controlling the firing of either one or two air conditioner compressors. By working in conjunction with your air conditioning control board, this relay delivers accurate and reliable results.

Open your door to the world of heating with the LENNOX Heat Relay. This communication device communicates between a thermostat and an HVAC system. It lets you monitor and control heating equipment costs while optimizing comfort and efficiency.

The 14B05 Heat Relay is a 2-wire, single pole, 15 amp heat relay. It has two separate terminals and a 1/4" male quick disconnect on the load terminal. This heat relay can be used as load in normally closed thermostat applications. The heat relay can be used for heating and reheat applications.

The 14B05 is a replacement/upgrade heat relay for Lennox air conditioning units. The item is used when the original heat relay has failed and needs to be replaced. This heat relay is designed to operate at extremely high temperatures, and will work effectively when wired in parallel with other identical heat relays. This item may need additional installation hardware, so please verify your existing heat relay(s) is/are compatible with this part before ordering by using the compatibility feature found in the product analysis page of our website.

Powerful, continuous duty heat relays for use on multi-zone heating and cooling systems. The B05 relay control features stainless steel protection against high corrosion in industrial and commercial air handling environments.

The 14B05 is a normal cooling heat relay that replaces the 13Z5. It has a mounting height of 4 inches, length of 6.25 inches, and width of 2 inches. Cooling heat relays are used to switch electric current on or off and consist of two switches in series with each other. The switches are connected across an electrical circuit that is either hot or open depending upon the position of the first switch.
