6.2.1 Pump
Evinox ModuSat® unit has an integral Wilo Pulse-width modulation
(PWM) circulation pump.
Please note: When the unit is switched over to heating mode the pump
will run for 2 mins prior to the heating PICV opening, this is not a fault
in the unit but a normal control function as the HIU assesses the
current heating circuit flow temperature.
