Other modes for switching the unit on/off

In addition to the on/off modes described in the previous paragraphs (see section 8.1 and 8.2.1), there are three more ways to switch the unit on and
off:
• ON/OFF from Mitsubishi Electric system remote controllers.
• ON/OFF from digital input.
• ON/OFF from time bands.
9.3.1

Switching on and off via digital input

Only if the digital input is fitted.
Open the "user menu" and check that the "On/Off enable from digital input" parameter is set to "Yes".
When the contact is open the unit is "Off", when the contact is closed the unit is "On".
Proceed as follows:
• Switching on: close the remote On/Off contact. The "On from digital input" message appears in the main mask to show that the unit has been
switched on.
• Switching off: open the remote On/Off contact. The "Off from digital input" message appears in the main mask to show that the unit has been
switched off.
9.3.2

Switching on and off by time bands

Make sure that the "Clock board not installed" is not displayed in the "clock menu".
Check that the "Time bands enabled" parameter in the "user menu" is set to "Yes".
• Switching on: Set the required switching on time in the "clock menu". The unit switches on when the set time is reached. The "On from time bands"
message appears in the main mask to show that the unit has been switched on. Note: The unit does not switch on if it is set to "Off from keypad" or "Off
from digital input".
• Switching off: Set the required switching off time in the "clock menu". The unit switches off when the set time is reached. The "Off from time bands"
message appears in the main mask to show that the unit has been switched off.
After enabling time bands from the "Enable time bands" parameter in the "user menu", time bands can be set and different setpoints can be specified
according to requirements.
Several time bands (up to 10) of different types (A, B, C and D) can be set during the day.
The beginning of the first band is set to 00:00 and the end of the tenth band is set to 23:59; the end of one band determines the beginning of the
following one.
To use a smaller number of bands, set the time a band ends to the same time it begins, and that band will be ignored. Summer, winter and DHW
setpoints can be set for each time band (when applicable). It is also possible to define whether the unit must be on or off; set "Off" to maintain the unit in
"Off from time bands", set "Adjustment" to switch the unit "On from time bands".
The following chart shows some examples representing the default settings indicated in the clock menu for bands A, bands B and bands C. The chart
after that is a weekly setting showing bands A for Monday, bands B for Tuesday, Wednesday, Thursday and Friday, band C for Saturday and time bands
off for Sunday (with the bands disabled, the unit will stay to "Off from times bands").
