Install the temperature sensor in the middle of the cylinder
and establish the electrical connections
Ensure the temperature sensor and sensor
pocket make good contact.
▶ Make sure that the temperature sensor is
positioned correctly in the sensor pocket so
that the temperature will be measured
accurately.
▶ Install the installation set (Fig. 7, [1]), the temperature
sensor connected to the accessories (Fig. 7, [2]) and the
temperature sensor connected to the controller (Fig. 7, [3]),
and position them as shown in Fig. 7.

Install the temperature sensor at the inlet for the internal
indirect coil and establish the electrical connections
Ensure the temperature sensor and pipe make
good contact.
▶ Thermally insulate the temperature sensor so
that the temperature at the inlet for the internal
indirect coil can be measured accurately.
▶ Position the temperature sensor connected to the
accessories (Fig. 8, [1]) as shown in Fig. 8.
▶ Fasten the temperature sensor to the pipe using the plastic
spiral supplied (Fig. 8, [2]).
▶ Wrap the temperature sensor in insulating material (Fig. 8,
[3]).
▶ Secure the insulation using the 2 cable ties supplied (Fig. 8,
[4]).
▶ Connect the temperature sensor in the terminal box; use the
