Purpose
GAZDA G-105 thermostats are designed for automatic temperature maintenance in various heating, cooling, ventilation systems, as well as production technological lines.
Device Description
GAZDA G105 is a digital thermostat with an external temperature sensor, two relay outputs for connecting actuators, and an input for connecting a temperature sensor.
The G105 models differ in their functional purpose:
-
G105-KS is a general use thermostat, voltage-free COM-NC-NO output contacts. Output relays switch simultaneously.
-
G105-NS is a general use thermostat, but the contacts of the outputs with the switched voltage of the supply network (N/L-NC/L-NO), the output relays are switched simultaneously
-
G105-KZ - thermostat-controller of the heating system, contacts of the COM-NC-NO outputs without voltage, delay in switching on the "Boiler" output after switching on the "Pump" output. Delay in Disabling the Pump Output After Disabling the Boiler Output
-
G105-NZ is a thermostat-controller of the heating system, at the contacts of the outputs with the switched voltage of the supply network (N/L-NC/L-NO), delay in switching on the output "Boiler" after disconnecting the output "Pump". Delay in shutting off the "Pump" output after disconnecting the "Boiler" output.
The 'Work' command for the two-wire input is executed by closing its contacts.
Controls and Displays
The front panel of the GAZDA G105 thermostat contains:
1. Tri-digit display
2. The "+" button to increase the numerical value of the temperature
3. "-" button to lower the numerical temperature value
4. "OK" LED - indicator of shutdown by an external control device
5. Pump Output Indicator LED(1)
6. LED - Heater Output Indicator(2)
Safety Measures
The device operates at a voltage that poses a risk to life.
When operating and maintaining the device, it is necessary to strictly comply with the requirements of the rules for the technical operation of consumer electrical installations and safety rules.
The device must be operated in an non-hazardous area with a relative humidity of up to 80%.
The atmosphere of the room should not contain dust, acids, alkalis or other aggressive substances.
Never supply any voltage to the control input.
The connected load must not exceed the power specified in Table 1, item 6.
It is forbidden to open the body of the appliance if the power is connected to the mains cable.
The device should not be installed on wooden or other combustible surfaces (e.g. walls).
