Installation of Thermostat, Sensor Tee and Check Valve
Sensor Tee
•
Ensure that the Sensor Tee is fitted on the flow line between the appliance and the
header tank.
•
This is to be fitted as close to appliance to allow an accurate gauge of the water
temperature.
Follow wiring diagram.
•
This should be fitted with “Hemp & Paste”
Thermostat
- Refer to wiring diagram
•
The thermostat is to be connected to the pump – the pump activated to turn on when
the set temperature is reached.
•
Ensure that pump is fitted with 2 sensor tee’s and 2 thermostat’s: One thermostat to
trigger the pump to turn ON at 15
°
C. The other thermostat to turn the pump OFF at
55
°
C allowing a consistent circulation between the appliance and the BCU.
•
BCU is to be fitted with a thermostat that is activated to come on at 15
°
C.
Follow
wiring diagram.
•
The secondary pump in the field, which is branched off the flow line, is ideally set to
65
°
C to begin with – this can be increased or lowered depending on the application.
•
The goal is to pull the water off before boil point in the header tank.
Check Valve
•
Check valve to be installed above pump on the flow line, minimum 200mm below
header tank.
This will reduce thermosiphoning, ensuring heat is pulled off the boiler and not the header
tank.
