INPUTS/OUTPUTS
Inputs marked with * are related to congurable options and
they should be connected only if these features are enabled
and congured (see manual).
The inputs marked with ° are completely optional.

1: AHU. 1 coil (heating).
Set point room temperature control with minimum limit on sup-
ply. 2-stage electric coil (optional).
Room humidity control by modulating damper positioning.
TANK. Set point proportional control of tank water, with tank
water max. temperature limit (optional).
2:1 + Service water. Proportional control of set point water tem-
perature.
3:1 + Generic Loop. Set point proportional control with 0-10V
sensor or resistive sensor input. DIR/INV action set by LCD.
The controllers are able to manage the following applications; they are activated by setting the “tPCO” conguration parameter
on the display.
APPLICATION AND USE
MOUNTING
Mounting on DIN rail.
Avoid to mount the device in damp and dirty areas; it is suitable for using in environment with ordinary or normal pollution. Make
sure to leave enough space around the cooling slots of the device.
ELECTRICAL CONNECTIONS
Warning! Make the electrical connections only when the device is switched off. For the terminal rate see the label on the hous-
ing.
Do not exceed the max allowed current; in case of surplus loads, use a meter with appropriate power. Make sure that the power
supply conforms to the one required by the instrument.
The temperature sensors are not polarity-sensitive and can be extended using an ordinary bipolar cable (it is necessary to under-
line that the extension of the sensor may affect the instrument use as regards the EMC electromagnetic compatibility: the wiring
must be carried out with care).
The active sensors are characterised by a specic polarity which must be respected. It is necessary to ensure that the signal
cables (temperature/pressure sensors, digital inputs, TTL serial, RS-485 serial) are routed separately from hazardous voltage
cables. Controlli sensor use is recommended; get in touch with Sales Department for code availability.

USE TERMS - ALLOWED USE
For safety reasons the instrument must be installed and used according to the instructions provided and in particular, in normal
conditions, dangerous voltage parts must not be accessible.
The device must be adequately protected from water and dust according to the application and must also be accessible only using
tools (except for the front part).
The device is suitable for inserting into a device for home use and/or a similar one in HVAC applications and it has been tested in
relation to the safety aspects on the basis of harmonized European standards.
UNALLOWED USE
Any other different use is forbidden.
Please note that the provided relay contacts are functional and they can be damaged: possible protection devices foreseen by the
rules in force or dictated by common sense for obvious safety reasons, should be carried out outside the instrument.
