If the hot water tank is a distance from the boiler, wiring to it may be
impractical.
If hot water priority is important then the Return Sensor should be fitted
to the Hot Water Tank Return Pipe. If this is also impractical, then fit
as normal to the main Return Pipe and set the Minimum Return
Temperature to provide an adequate level of hot water supply.
Where the tank option is used, set the Minimum Return Temperature
to the stored water temperature requirement.
External Sensor
The External Sensor should preferably be positioned on a north facing
exterior wall, and connected to the appropriate terminals of the TEC 100/200.
If it is not possible to mount the sensor on a north facing wall, then mount
in a shaded position, under eaves, and away from boiler house vent grilles etc.
Note A special reflective, insulated external sensor is available when fitting
in a position where solar heat is unavoidable.
