Temperature drops lasting over a week or temperature drops that
differ from the normal week program are done with thespecial ca-
lendar. The special calendar is stronger than the week calendar.
It is easy to make a temperature drop with the special calendar,
e.g., when going on a vacation for a longer period of time. If the
controller’s pre-increase function has been taken into use, set the
time you are returning home as the end time. Select “Automatic” at
the ending time . The pre-increase ensures that a nominal tempera-
ture will been reached at the ending time (see p. 47).
The control command symbol that appears in the EH-800 controller’s
basic display automatically changes according to what is controlling
heating levels. When the control command comes from the set ti-
me program (week/24 hour clock or special calendar), a symbol of a
clock appears in the main display.
The amount of temperature drop is given in settings (see p. 11).
The pre-increase function can be used when switching from a tem-
perature drop to a nominal temperature. (see p. 47)
In this example, there is a big temperature drop from 21.12.2009 to
03.01.2010 and then the controller switches to a nominal temperatu-
re mode if the week program or Home /Away control doesn’t cont-
rol the temperature drop.
A temperature drop for a certain length of time is made using the
exception calendar as follows:
Move to exception calendar and press OK. Press OK at the “Add
new” row.
Press OK and set the time (date and time), for the tempe-
rature drop to begin. Press OK.
Press OK at the mode row and select the mode for the controller to
switch to at the above set time. You can select “Temperat. drop”, “
Bigger temp. drop” or “ Contin. nominal temperat.”.
Press ” Ready” to confirm exception calendar control.
The Home/Away control is only in effect if the controller is on auto-
matic control. When you send a Home or Away message, the cont-
roller sends back an OUMAN message showing that the HOME or
AWAY control is on.
Deleting a temperature drop from the exception calendar:
Select the switch moment to be deleted at mode
“Delete switch time” and select “Ready” to confirm.
