1. INTRODUCTION
The thermostat-humidistat terminal is an instrument that can, according
to the model chosen, control the ambient temperature and humidity.
It can be used in various operating modes, which are described in this
manual. Depending on the model, the following functions/components
are included:
Built-in NTC temperature and humidity sensor with digital measurement. •
Available on all humidistat codes, not available on thermostat-only
codes.
Remote NTC temperature sensor, with speci c temperature •
compensation functions in the controller.
Digital input from voltage-free or 24 Vac contact, with control function •
for alarms, on/o , etc.
0 to 10 V output for controlling humidi ers, air-conditioners or •
condensing units.
Two relay outputs with class 2 insulation from the rest of the instrument •
for controlling the actuators.
Advanced algorithms for operation in heating, cooling or automatic •
mode. Special functions for the control of under oor heating, radiant
 oors in cooling mode and temperature compensation functions.
Timer and RTC clock for day and night operation
Display in degrees Celsius/Fahrenheit•
Serial option for remote control by supervisor.•
1.1 Models available
CLIMA controllers
The clima controller is available in various hardware models, which
correspond to di erent possible combinations and operating modes. The
following tables describe the possible operating modes for the various
hardware models and the speci c features of each model.
The various operating modes can be selected using the dipswitches at
the rear of the instrument, as explained in chapter 4 “Con guring the
operating modes”.

T
√√√√
Basic temperature control only with one relay only (R2). The analogue output is associated with
the temperature..
T2
√√
Two-stage temperature control only, with two relays (R1 and R2).
The analogue output is associated with the temperature.
T2A
√√
Two-stage temperature control only, with two relays (R1 and R2) and automatic control of
cooling/heating mode. The analogue output is associated with the temperature. Other settings
for this mode are available by parameter.
See the chapter on “Functions”.
H
√√
Basic humidity control only with one relay only (R2) associated with humidi cation or
dehumidi cation control. The analogue output is associated with the humidity.
T+H
√
Temperature and humidity control. One relay is associated with the temperature (R1), the other
(R2) associated with humidi cation or dehumidi cation control. Analogue output associated with
the humidity.
T2+H
√
Two-stage temperature and proportional humidity control. The two relays are associated with the
temperature (R1 and R2), the analogue output is associated with the humidity.
T2A+H
√
Two-stage temperature and proportional humidity control with automatic control of the cooling/
heating mode. The two relays (R1 and R2) are associated with the temperature, the analogue
output is associated with the humidity. Other settings for this mode are available by parameter.
See the chapter on ‘“Functions”
T+H radiant ON/
OFF
√√√√√
Model for radiant systems, with ON/OFF control.
Temperature control only or temperature and humidity control, according to the model
purchased.
If humidity control is available, the analogue output is associated with this.
T+H radiant
proportional
√
Model for radiant systems, with proportional control.
Temperature and humidity control.
