Honeywell L7248A Q & A

Can the l7224a and l7248a be used with 24 VAC thermostats?

• The L7224A,C and L7248A,C,L are designed for use with 24 Vac electronic and electromechanical thermostats or EnviraCOM™ enabled thermostats, and have screw-type terminals for easy field connection.

• On the L7248 models, the High Limit, and Anti Short-Cycle time are also adjustable, see “Adjusting Settings”. The overall range of the High Limit is from 130 °F to 240 °F (54 °C to 116 °C). Select devices may have different ranges. Some models have limited ranges on the High Limit setpoint; this limited range is listed on the device label.

What are the settings for the l7224 boiler?

• On the L7224 models, the High Limit, Low Limit, Low Limit Differential, and Anti Short-Cycle time can be adjusted to the setting recommended by the boiler OEM.
