3.1 Daily operation
Daily operation is also described briefly in the folded set of user's instructions to be placed under DOL
78T' front lid.
.
The required emergency temperature, at which emergency opening must take place, is set by means of the
rotary switch on the front of DOL 78T.
When the switch is turned, the climate computer display automatically shows the climate computer set
point (required house temperature) as well as the setting of the DOL 78T emergency temperature switch
for a few seconds. The emergency temperature should be set approx. 4 degrees above the climate com-
puter set point (required house temperature).
Example:
Set point, house
Î
Set point, em. open. 30
If the climate control unit is in batch operation, where the house temperature is automatically lowered
slightly every day, the DOL 78T switch must be adjusted regularly in order to follow the temperature
lowering of the climate computer. If the DOL 78T emergency temperature is not lowered so that it is
o
more than 6
higher than the climate computer set point, the warning "Emergency temperature too high"
will flash in the climate computer display.
