10. ANtI FREEZE PRotECtIoN
two different anti freeze limits are used. both are active with the compressor on and off and are activated by either
lWt or eWt sensors.
²
the first limit is a 6°c the actions are:
start the internal pump
switch off the compressor
²
the second limit is at 4°c, the actions are:
if the unit is in off mode then switch on.
allow the internal electric heaters to start if a room terminal is connected.
start the plate heat exchanger heater
if the heat pump is started up in winter in cold conditions the compressor will not be able to start.
if the room terminal is connected then the electric heaters or boiler will switch on to heat so the
compressor can then start. if no room terminal is connected then use the emergency heat switch next
to the display to start the back-up heat.
11. ALARM LoG
the
Aqu@ Scop Advance DCI
will store the last 20 alarms in chronological order. each alarm is memorised
with an alarm code, time, date, eWt, lWt, oct and oat. if more than 20 alarms occur the oldest alarms are
automatically deleted.
after entering the alarm list from "err" the last alarm is always displayed. it is possible to scroll through the alarm
list but the way to identify the last alarm is either to look at the time and date or to exit the alarm menu and enter
it again.
