Use Of The Commissioning Switch - Evinox ModuSat FS Series Installation Manual

6.3

Use of the commissioning switch

The commissioning switch is located inside the case of the ModuSat next to the
manometer and heat meter display. This switch enables the unit to be put into a manual
heating 'on' mode prior to full unit commissioning to enable the testing of the secondary /
apartment heating circuit. Please note that this function should not be used until the
secondary installation is complete i.e. flushed, treated and refilled to the correct pressures.

To enable the heating run mode setting the button should be depressed and held in for
approximately 30 seconds. The 3 port diverter valve will then fully switch over to heating
mode (Port A). The unit will then run at a pre-set output temperature of 45°C thus
providing a safe temperature for UFH circuits and also a gentle warm up of radiator
circuits. This function will run for a pre-set period of approx. 45minutes.
Once the cycle has finished, the 3 port diverter valve will then divert back to DHW mode
(Port B) if the tank is calling for heat i.e. the tank is below the factory pre-set of 55⁰C. The
unit will remain in DHW mode until the tank temperature is satisfied whilst there is power to
the ModuSat.
If the heating needs to be run again, the process is repeated and then the cycle will start
and run for a further 45 mins.
Please note: The rocker switch above the commissioning push button is the Pump
Manual Override. This should NOT be operated or used by persons other than
Evinox Engineers as it is for emergency use only.
