OPERATION
Pump Exercise Function
During periods of inactivity (summer months or between installation and general use) a manifold circulating pump can
seize and cause problems when the system is reactivated. To help prevent this issue, the TEVO wireless wiring centre has
an optional ‘pump exercise’ dip switch (SW3) which, when selected to ON, will operate the pump for 5 minutes once every
month.
Pump Delay Function
Commonly, the electrical thermal actuators which open the individual loops will take up to 5 minutes to fully open. The
pump delay function will then delay activation of the manifold circulating pump by 3 minutes, from activation, in order to
allow the vales to fully open.
