APPENDIX F - CASCADE CONTROL & ADDITIONAL MIXING CIRCUIT

To Convert the boiler hydraulic diagram for cascade control & additional mixing circuit :

Before programming changes are made, ensure the boiler is set to standby mode.

Press and hold both up and down arrow keys for at least five seconds to enter advanced parameter list H90
displayed top right of HMI screen.

Use either up or down arrow key to scroll through the parameter list and stop at H552

Default value is 2

Two options are available.

Option 1 - for use with the Merley sequence controller

To enable cascade control change the setting by using the + or – key and set value to 80.

Press mode button to store change and return to home screen.
