Parameter Descriptions
Note: If a button is not pressed for 10 seconds while using the control panel it times out and reverts to standby mode.
When parameters are being set the Setpoint LED will flash on the display.
Note: Your POLAR appliance has been preset with default parameters generally deemed suitable for normal operation (see “Default
Parameter Values” on page 3). POLAR recommend these preset vlaues are used.
Note: The control panel will automatically move to the next parameter. To return to standby mode allow the control panel to time out.
