I recently installed aTeledyne Laars boiler and tested the system using the old existing thermostats. Everything worked great. Then I installed a Honeywell T8600D programable themostat on one of the zones. When this new thermostat calls for heat, it will start and stop the boiler at least five times before it will let the boiler stay on and warm the house. Any help or advice would be greatly appreciated.
