Flexitemp Instructions - Euroheat

B) Toby Flexitemp Part Number MS10040
Electrical oil valve control with the Flexitemp.
1 2 3 4 5 6
The Flexitemp allows the oil valve to be controlled automatically, and can be used to govern the firing rate of a
stove with a boiler as illustrated in the two following drawings. High and low limit thermostats are incorporated
to protect the boiler from condensation by not allowing it to run at too low a temperature and dissipating
excess heat should the control thermostat fail. The high limit and control thermostat should be fitted at the
boiler flow outlet and the low limit thermostat should be fitted to the boiler return inlet. All pipe thermostats
must be fitted using heat conducting paste between the thermostat’s monitoring face and the pipe to ensure
reliable thermal transmission. High temperature cables must be used to wire components in contact with or
in close proximity to the stove. All wiring must be in accordance with whatever regulations may be applicable
at the time of installation.
