DDSTAT commercial controller

Hot water system thermostat

DDSTAT commercial controller

The DDSTAT thermostat operates by measuring the temperature of the water in the storage cylinder. If the temperature of the water is below the set point the controller will switch ON the pump(s) that circulate water from the cylinder through the gas continuous flow water heater and back to the cylinder.

Features:
• Dual pump arrangement for duty/standby operation

• Inbuilt system error detection, which can be connected to an external BMS system

• Optional second probe (sensor lead kit R5049) that can be utilised to detect hot water return temperatures from Rinnai INFINITY units
