Basic information:

IB-Tron 1000 GWC controller is independent microprocessor controller with large LCD display. The controller is designed to control work of valves, air dampers, electric air heaters, pumps, fans and other two- and three-point controlled appliances (on/off).
IB-Tron 1000 GWC controller allows to control process of heating, cooling and ventilation. The thermostat chooses source of heat or cold in intelligent way including testing periods. An example of this type of installation is controlling of ground heat exchanger (GHE).
A professional and intelligent controller to control systems where you have to choose source of heat or cold from two different sources! This is not a simple differential controller!

• 1x Operating manual
  
• 1x Operating manual for network (only with NW model)

General considerations:

• The controller is for surface-mounting, it sticks out 23mm.
  
• In the controller a relay box is separately on the 20cm wire and dimensions 30/50/65mm
  
• Built-in RT sensor is complete with thermostat. FT sensor isn't supplied with thermostat.
  
• RT sensor is on the 20cm wire and it can be bring out at the back of casing.
  
• RT sensor can be extended according to needs or it can be replaced by another type of sensor (if it's needed)..
  
• Change of RT sensor doesn't invalidate the warranty.
  
• The controller gives 230V voltage on the output (support of pump, valve, air damper, heating mat etc.). If thermostat has to operate normally open/normally closed device, so-called: contact device (for example: gas heating stove), it will be required additional normally open/normally closed relay. We have these relays in our offer.
  

Structure:

Connection:

• 1 - 2 - FT sensor
  
• 3 - 4 - power supply 230V AC
  
• 5 - A phase appears (L) when choosing FT source
  
• 6 - A phase appears (L) when choosing RT source
  

Two loose wires with thermistor come out from the controller, it can be cut and connect external RT sensor

Operating principle:

In the controller we have to set three time values:

• Testing break - value in minutes specifying, at what time do the measuring test. This value depends on devices, which 'receive' heat or cold and more precisely depends on how often the temperature conditions may change in this device. In the typical size of GHE (typical family house) this value is most in the range of 10 ÷ 30 minutes.
  
• Testing periods - value in seconds specifying, how long device has to work before reading of sensor reaches the appropriate level of temperature (starting period, starting delay ). Testing period is set separately for each device.
  

In case of installation of GHE the first device is directly external inlet probe and sensor has to be placed near to the inlet probe (direct measurement of external temperature). Testing period of this device should be set to 0 (there isn't any delay, the reading is current). The second device is GHE. Delay of this device should be set to optimal value for the GHE - mostly it's time to move air through the GHE (it depends on length and size of GHE). For the typical size of GHE (for typical family houses) this delay is in the range of 20 ÷ 120 seconds.
Depending on the mode in which the controller operates (heating or cooling), device chooses warmer or colder device.
The controller is intelligent. It means that it remembers readings and change the temperatures on the both devices. For example: when controller during data analysis determines that there is probability of more favorable temperature conditions on the second device than currently used device, may be earlier testing of the second device.

Example of operating:

Typical GHE installation. The controller is designed to decide from where take the air:

• from the GHE - there is closing of the air damper with actuator from the external inlet probe. The air damper with actuator is opening from the GHE simultaneously and the controller starts the GHE fan.
  
• from the external inlet probe - there is closing of the air damper with actuator from the GHE and turning off the GHE fan. The air damper with actuator is opening from the inlet probe simultaneously.
  

Testing period of inlet probe is set on 0 seconds (current measurement without delay). RT sensor is placed near external inlet probe so as to measure the outside air temperature (shady, sheltered from the wind and moisture place).
Testing period of GHE is set on 30 seconds (this is air flow from the onlet probe of GHE to recuperator). FT sensor is placed in the ventilation duct from the GHE before the recuperator.
Testing break is set on 15 minutes.
Heating mode is set (selection of a hotter heat source). In the summer the controller by pressing single button switches onto the cooling mode to cooling the building.
Exemplary logic of device operating:

• The air is taken from the GHE.
  
• When the outside temperature is found to be higher than the air temperature from the GHE, the controller will switch devices so that the air was taken from the external inlet probe (it happens immediately because testing period of inlet probe is set on 0 seconds but including hysteresis).
  
• If the outside temperature falls below the last memorized temperature which was on the GHE or from the appropriate algorithm, the controller "suspects" that air temperature from the GHE will be higher than outside temperature or 15minutes (testing break)have passed since the last switching air dampers. The GHE is turning on (on thirty-seconds testing period). After the test, the controller decides from where take the air.
  

In our offer are available air dampers with actuators with different cross-section.

Example of Controlling Water Heat Exchanger:

IB-Tron 1000 GWC controller measures two temperatures: outside temperature (by RT sensor) and air temperature after passing through the heater, when water circulation pump is turned on (glycol or brine), by FT sensor. Measurement of the outside temperature (RT) is current, measurement of air temperature (FT) at the switching on heater has to be cyclic.
Testing period should be as short as possible but has to ensure proper stabilization of the air temperature after passing through the heater (installation which leads water, heater and air from the heater has to warm up).
If the controller after this testing period recognizes that favorable temperature conditions provides water heat exchanger, the pump still works and measurement of FT temperature is current. Measurement of RT temperature is current too, so if favorable temperature conditions are at the external inlet probe, the P1 pump will be turned off.
If favorable temperature conditions after testing period are still at the external inlet probe, P1 pump is turned off. The pump is again turned on only after testing period.

Calibration

After proper connection the controller is ready to work. The controller is factory calibrated to work with standard sensor. However, with long wires, displayed temperature may be different from real temperature.
In this case you have to calibrate the device by yourself:

Clock and day of the week:

Time can be displayed in 24-hour system or 12-hour system.

Temperature units:

Temperature can be displayed in ºC and ºF

Work mode:

The controller can work in two modes:

• Heating mode (selection of warmer source)
  
• Cooling mode (selection of colder source)
  

Hysteresis:

Hysteresis means a delay in switching on/switching off the device. If it's higher value of the hysteresis, controlled device performs less cycles (e.g: air dampers) - therefore vitality of the device increases.
In normal conditions it's recommended to set hysteresis value to 1ºC. Value setting of hysteresis depends on where is the measurement (e.g. for liquid suggested is higher hysteresis).

Keyboard lock:

To protect controller from unwanted change settings, you can lock controller keyboard.
When keyboard lock is activated, on display is visible a padlock symbol and keyboard doesn't respond to pressing keys.

GUARD function:

If the controlled device (e.g.: air damper, valve or pump) is not working for a long period of time, it may be damaged. Therefore it is important that each element was periodically turned on even when there is no need from point of view of system logic.
This protective function is GUARD function. It monitors work of controlled devices. If the device doesn't change its status of the operating by 240 hours, the controller changes the status for 20 seconds.

Test of Relays:

TEST function is used to check the controlled device (e.g.: air damper) - if it's well connected and working properly.

Modes of Temperature Displaying:

Controller can display RT and FT temperature in three modes:

• AF - alternating, RT and FT temperature are displayed every few seconds.
  
• A - RT temperature is continuously displayed.
  
• F - FT temperature is continuously displayed.
