Please Note:

• A chronoproportional (or TPI) room thermostat makes boilers operate more efficiently and provide close accurate control. Chronoproportional control is a load compensator as it ensures that the boiler ’ON’ time is reduced to a minimum and matches the boiler heat output with the heat loss.
