FLOW TEMPERATURE SENSOR
The EcoKnight water heater requires a temperature sensor to be installed in the primary flow pipework. On single
water heater installations and multiple water heater installations that will not use the integral cascade manager, the
sensor needs to be installed as close to the outlet of the appliance as possible. On cascaded installations, the sensor
should be installed on the common flow pipework as close as possible to the junction where the individual water
heater flows meet.
The appliance is supplied with two sensors, from which only one should be chosen.
10.6.1
DRY-POCKET SENSOR
A 6.35mm sensor and pocket are supplied in the fittings kit in the front cover of the appliance. Provision should be
made to install this sensor in the flow pipework in the required location, ensuring that any reducing fittings used allow
the pocket to by sufficiently immersed in the water flow to correctly register the temperature.

STRAP-ON SENSOR
Where it is not possible to fit the dry-pocket sensor, the strap-on pipe sensor can be used. The sensor should be
positioned on the primary pipework in the required location – ensuring the contact pad remains in place – and
secured with the supplied tie.
