
For RT series tanks, a thermostat well is supplied which needs to be fitted
to the fitting (2
Fit sensor well here

For 610 series tanks, remove the plastic cover from the fitting located 90
from the water connections on the storage tank, but do not discard.

Make a small hole in the centre of the plastic cap and thread the sensor
through the hole.

Insert the sensor all the way into the thermostat well and fit the plastic cap
back onto the storage tank.

To prevent the sensor dislodging from the well, screw the cable to the tank
jacket using a cable clamp.

Cable tie the sensor lead, curling up and tying off any excess lead.
Building Flow Temperature Sensor Installation

Connect the 2
pump marked "Building Flow Sensor".

Run out the sensor to the building flow pipe.

Fit a thermostat well (not supplied) in the pipe ensuring the end of the
sensor is in the flow of water. To prevent the sensor dislodging from the
well, secure the sensor to the insulation using a cable tie. Alternatively,
clamp the sensor to the outside of the pipe using a pipe clamp prior to the
insulation being fitted.
Note: For multiple heat pump installation, the preferred method is to interconnect
the heat pumps (up to 4 maximum) via LAN cables, available as an accessory
(part number: 17534).
In this case, only one tank sensor and building flow temperature sensor is
required, which are connected to the heat pump designated as the Master.
Alternatively, each heat pump can operate independently in which case each
tank sensor and building flow temperature sensor must be connected and fitted
as described above.
