TERMISTAT–6–2S–485–LCD controller
TERMISTAT–6–2S-485–LCD is a microclimate controller that controls work of fans and heaters depending on temperature and time (function of periodical ventilation). It has got two control outputs: one is electronic with fluent power control (Section 1), the second one is a relay output, voltage-free of ON/OFF type (Section 2). For extension of the system and its functionality the controller is equipped with a RS-485 digital bus for interoperation with extension modules of the JOTAFAN system.
It enables additional connection of:
- up to 8 extension modules of fluent section (MODUŁ 6A, MODUŁ 6A-010),
- up to 4 controllers of servomotors inlets (INLET-010),
- extension of the number of ‘ON/OFF’ sections- up to 8 independently programmed sections (Module 4ZW),
- RHT-01-GN temperature and humidity sensor,
- Module 010-2S to generate analogue voltage 0..10 V for fluent control of devices (power inverters, servomotors inlets, etc.).,
The controller has got two relay alarm outputs and it indicates alarms e.g. when the set temperature thresholds are exceeded (temperature is too low or too high), in case of power supply failure, temperature measurement line damage etc.
Wiring diagram of the TERMISTAT-6-2S-485-LCD controller with sensors and modules control:
Characteristics:
- temperature measurement is made by means of digital sensors, the possibility of connection of up to 4 sensors TEMP-201, one sensor is included in the set,
- temperature and ambient relative humidity measurement (RHT-01-GN),
- two built-in control sections (each can work as ventilating or heating),
- a RS-485 module for communication with other JOTAFAN devices (extension modules of ‘fluent’ section, controllers of servomotors inlets, etc.),
- Section 1, ‘fluent’ – it enables the multistage (100 stages) control of single-phase fans or infrared illuminators with current up to 6A,
- Section 2, ‘ON/OFF’ type- with a relay output, voltage-free (NO and NC contacts of a relay, load current capacity up to 3A),
- relay alarm output (NO, NC and COM contacts), 24V, 200mA,
- large, easy to read display LCD with messages in Polish.
Functions:
- choice of the mode of outputs operation (ventilation/heating),
- change of the stage of section operation and thermal alarms by means of one parameter: preset temperature,
- defining the minimum and maximum control of the fluent section,
- a 'forbidden range' – elimination of the part of the fluent section control range that is energy-intensive and adverse for work of fans,
- periodical ventilation: setting the cycles and levels of ventilation, bandwidth of ventilation (shortening the time of ventilation together with lowering below preset temperature in a building),
- alarm function i.a. when temperature thresholds are exceeded (temperature is too low or too high), when the control process has been stopped, in case of power supply failure, temperature measurement line damage etc.,
- diversity of characteristics of inlets operation in terms of the fluent section in order to generate differential pressure,
- the possibility of declaring the sensor of external temperature (i.a. in order to correct an alarm threshold or when temperature is too high),
