5.4 Connection of external circuits
Operation as circulation thermostat
−
Connect 11-12 mm int. dia. tubing (
➾
Section 5.3.) to
the pump connector
−
Pump outflow connection always in front, return
connection always at the back.
☞
−
If the cross-section of the tubing is too small
!
temperature drop between bath
and external system due to low flow rate. Increase the bath temperature
appropriately.
−
Always ensure the maximum possible flow cross-section in the external circuit!
−
When the external consumer is placed at a higher level than the thermostat the
pump is stopped and air penetrates into the thermostating circuit the external
liquid may drain down into the bath even with a closed system
!
danger of
flooding the thermostat
−
Protect tubing with hose clips against slipping off!
−
When no external consumer is connected to the thermostat, the pump outflow
connection must be closed (use closing plugs) or linked to the return!
−
Using the setting knob at the pump outflows, divide up
the pump flow in accordance to the thermostating
task.(

−
Operate the setting knob only when the bath contents are near the ambient
temperature.
