Thermostat will not go below 60 when setting temperature for 55 degrees while trying to lower temperature.

Thermostat in heating setting - not the cooling setting.

Thermostat will not go below 60 when setting temperature for 55 degrees while trying to lower temperature.

Is the thermostat designed not to go below 60 degrees or is there a setting or way that it will go below 60 degrees?

Unit apparently defective as exchanged and new one working fine.

Thanks for the update. Always nice to hear how things worked out.

How can I replace Honeywell.Lr1620.Class2 with Rth6400
