Customers thermostat showing low battery. They said they’ve tried several batteries and it’s not helping. Fan will run when setting the fan on I will not call for heating or cooling. Provided options for thermostats on page hh5. I wanted to go with T4 pro thermostat. Cycled system on heating and cooling. Showed customer thermostat operation. Customer will set schedule up later. Gave customer,er user guide for thermostat. All okay at this time.
