1 GENERAL ADVICE
PLEASE READ BEFORE USING THIS MANUAL
• This manual is part of the product and should be kept near the instrument for easy and quick
reference.
• The instrument shall not be used for purposes different from those described hereunder. It cannot
be used as a safety device.
• Check the application limits before proceeding.
SAFETY PRECAUTIONS
• Check the supply voltage is correct before connecting the instrument.
• Do not expose to water or moisture: use the controller only within the operating limits avoiding
sudden temperature changes with high atmospheric humidity to prevent formation of condensation
• Warning: disconnect all electrical connections before any kind of maintenance.
• The instrument must not be opened.
• In case of failure or faulty operation send the instrument back to the distributor or to “Dixell s.r.l.”
(see address) with a detailed description of the fault.
• Consider the maximum current which can be applied to each relay (see thechnical Data).
• Ensure that the wires for probes, loads and the power supply are separated and far enough from
each other, without crossing or intertwining.
• Fit the probe where it is not accessible by the end user.
• In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel
with inductive loads could be useful.

4 DISPLAY LAYOUT
4.1 HOW TO READ THE MEASUREMENT LIST
With the icon Cir1 on, push UP or Down keys to display the labels of the information of the circuit 1.
With the icon Cir2 on, push UP or Down keys to display the labels of the information of the circuit 2.
Each measurement is defined by a label that indicates which if it is a pressure a temperature or a time.
4.2 READ PROBE VALUES OF CIRCUIT 1 OR 2
To swap between the information of the two circuits use the UP and DOWN key to select a label then
push SET, check the led.
Example in fig.1
Icon Cir1 is on: the top display shows the value of the output evaporator temperature (12.8°C) of the
circuit 1; the bottom display shows Out 1 (outlet temperature evaporator 1). Push SET key to swap to
the circuit 2. Fig2
Icon Cir2 is on: the top display shows the value of the output evaporator temperature (11.7°C) of the

5 DISPLAY INFORMATION
5.1 READ THE SET POINT VALUE
Push and release the SET key, the set value is displayed.
In stand-by the bottom display shows SetC (set chiller), by pushing SET again the next label is SetH
(set heat pump).
If the unit is running the only set displayed is related to the running mode.
5.2 MODIFY THE SET POINT
1) Push SET key for at least 3 seconds
2) Use the UP or DOWN key to modify the setpoint. In chiller it is possible to modify the chiller set
point, in heat pump it is possible to modify the heat pump set point, in std-by it is possible to

Chiller mode: push SET one time, the bottom display shows the SEtC (set chiller) while the top
display shows the set value. Only if the Energy saving or the Dynamic Setpoint are active, pushing
another time the SET key, the bottom display shows “SEtr” (real setpoint), and the top display shows
the setpoint that the unit is really using for the thermoregulation.
Heat pump mode: push SET one time, the bottom display shows the SEtH (set Heat pump) while the
top display shows the set value. Only if the Energy saving or the Dynamic Setpoint are active, pushing

7 FIRST INSTALLING
7.1 ON BOARD CLOCK (OPTIONAL)
Giving power supply the bottom display shows “rtC” alternated to a temperature or pressure value: It
is necessary to set the RTC (Real time clock).
ATTENTION
