1. INTRODUCTION
IR33-DN33 Universal is a series of controllers designed for controlling
the temperature in air-conditioning, refrigeration and heating units. The
models di er according to the type of power supply (115 to 230 Vac or
12 to 24 Vac, 12 to 30 Vdc) and the outputs, which based on the model
may be one, two or four relays, one or four PWM outputs for controlling
external solid state relays (SSR), one or two relays plus one or two 0 to
10 Vdc analogue outputs (AO) respectively. The models described in this
user manual are suitable for controlling the temperature using four types
of probes: NTC, NTC-HT (high temperature), PTC or PT1000. The type of
control can be set as ON/OFF (proportional) or proportional, integral and
derivative (PID). A second probe can be connected for di erential control
or freecooling/freeheating, or for compensation based on the outside
temperature. The range includes models for panel installation (IR33), with
IP65 index of protection, and for DIN rail mounting (DN33). To simplify
wiring, all the models are  tted with plug-in terminals. The controllers
can be connected via a network to supervisory and telemaintenance
systems.
The accessories available include:
computer-based programming tool;
•
remote control for operation and programming;•
programming key, with battery;•
programming key, with 230 Vac power supply;•
RS485 serial card;•
RS485 serial card, with possibility of reversing the Rx-Tx terminals;•
module for converting the PWM signal to a 0 to 10 Vdc or 4 to 20 mA •
analogue signal;
module for converting the PWM signal to an ON/OFF relay signal.•
