1 MEASUREMENTS AND INSTALLATION
For the dimensions and drilling template, see Figure 2 and Figure 3. Fit the controller to a panel
with the snap-in brackets supplied.
INSTALLATION PRECAUTIONS
- Ensure that the thickness of the panel is between 0.8 mm and 2.0 mm (1/32 in. and
1/16 in.)
- Ensure that the working conditions are within the limits stated in the TECHNICAL
SPECIFICATIONS section.
- Do not install the device close to heat sources, equipment with a strong magnetic field,
in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations,
or shocks.
- In compliance with safety regulations, install the device correctly to ensure adequate
protection from contact with electrical parts. Fix all protective parts in such a way so as
to need the aid of a tool to remove them.
2 ELECTRICAL CONNECTION
Important
- Use cables of an adequate wire gauge for the current running through them.
- To reduce any electromagnetic interference, connect the power cables as far away
as possible from the signal cables.
For the electrical connection diagram, see Figure 4.

PRECAUTIONS FOR ELECTRICAL CONNECTION
If you use an electrical or pneumatic screwdriver, adjust the torque to a maximum of
-
0.5 N•m (4 in. lb).
If you move the device from a cold to a warm place, the humidity may cause
-
condensation to form inside. Wait an hour before you switch on the power.
Make sure that the supply voltage, electrical frequency, and power are within the set
-
limits. See TECHNICAL SPECIFICATIONS.
Disconnect the power supply before you do any type of maintenance.
-
Do not use the device as safety device.
-
For repairs and further information, contact the Penn sales network.

3 FIRST-TIME
1. Follow the instructions in MEASUREMENTS AND INSTALLATION to install the controller.
2. Power up the device as shown in ELECTRICAL CONNECTION and an internal test runs.
The test normally takes a few seconds. When it finishes the display switches off.
3. Configure the device as shown in Table 6.1 in SETTINGS.
For recommended configuration parameters for first-time use, see the following table.
PAR. DEF. PARAMETER
SP 0.0 Setpoint
P2 0 Temperature unit of measurement
d1 0 Defrost type
Check that the remaining settings are appropriate; see CONFIGURATION PARAMETERS.
4. Disconnect the device from the mains.
5. Make the electrical connection as shown in ELECTRICAL CONNECTION without powering
up the device.
6. Power up the device.
