In this mode the controller will only heat during a timed-on period and when receiving sufficient flow.
If no or insufficient flow is being received no cooling will take place. When in a timed off period no cooling
will take place.
In this mode the controller will heat whenever it is receiving flow during a timed-on period.
8. TROUBLE SHOOTING
Chilling Device will not switch on
In most cases this will be the result of one of the following not being met:
Possible Cause 1.
The required temperature has been reached.
To confirm the controller is requesting the chilling device to switch on check that the
required temperature is at least 0.6⁰C greater than the current water temperature
and that the red thermometer in the display is ‘animated’ showing the thermometer
increasing.
Possible Cause 2.
Insufficient Flow.
The display will show
‘NO FLOW’
if the flow switch has detected that the flow
volume is below 4,000-litres per hour (4m³/h).
Check that the flow volume is greater than 4,000-litres per hour and that the flow
switch is in the correct orientation to sense flow (i.e. check that the arrow moulded
into the flow switch body is facing in the same direction as the flow travelling through
the T-Piece).
Possible Cause 3.
The controller is in a timed off period.
Check if the controller has the ‘TIMER’ symbol
displayed
– if it does check your
clock and time period settings (explained in the set-up section).
Possible Cause 4.
The chiller output has not been correctly connected to the control circuit of your
chilling device.
Check the wiring diagram for verification on how the controller should be connected
to the chilling device and seek the expertise of a qualified electrician if in any doubt.
Possible Cause 5.
The controller is in time delay mode.
If the display is showing
‘CHILLER DELAY’
the controller is in time delay mode.
This is activated if the controller is requesting the chilling device to switch on more
than once in a 2-minute period
– this can be caused by a fluctuating flow rate (just
above and then just below the 4,000-litre per hour requirement) or fluctuations in
water temperature.
To rectify check the plumbing for any restrictions to flow and increase the flow
volume. Also check the positioning of the temperature sensor, it should be
positioned on the entry port of the heat exchanger.
