1. INTRODUCTION

The CLIMA 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”.

√√√√

Basic temperature control only with one relay only (R2). The analogue output is associated with

the temperature..

√√

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”.

√√

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.
