Connection of external circuits
Operation as circulation thermostat
−
Connect 11-12 mm int. dia. tubing (for Types RE 3xx
use metal hoses) (
➾
Section 5.3.) to the pump
connector
−
Pump connection outflow 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!
−
On Types RE 3xx, when tightening the union nut hold on to the pump nipple with a
SW 14 spanner (see ill.)!
−
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 circuit is connected to the thermostat, the pump connection
outflow must be closed (use closing plugs) or linked to the return!
