The ECONO mode consists of 2 program settings. You can basically use this
function for an installation at a cottage/vacation home. The 2 program settings
run on a weekly basis. One setting is used to raise the temperature to a
comfortable level while you are there at the cottage, and the second setting is to
bring the temperature back down for energy savings while the cottage is vacant
during the rest of the week.
FOR EXAMPLE:
If you go to your cottage only during the weekends, then you can set the ECONO
programs as such:
P1 - SATURDAY - 8:30 am for 21 C; and,
P2 - SUNDAY - 5:00 pm for 15 C
This means the cottage will be heated at 21 C between Saturday morning at
8:30 am to Sunday evening at 5:00pm. For the rest of the week from Sunday
evening at 5:00 pm to the next Saturday morning at 8:30 am, the cottage will be
kept at a low temperature level of 15 C for energy savings.
