LED Smart temperature controller for ventilation system RS485
It controls the work of DC fans based on indoor and outdoor temperature. Control logic is smart, simple and stable, it can help energy saving. It output a start signal for ventilation system, through relay (free dry contact). It output a alarm signal when water in the floor (immersion) or frequency of fan is lower than 20Hz.
Function: | |
Set | 3 buttons to set. |
Display | 3 pcs of LED display temperature and alarm codes |
Temperature detect | 2 channels, detect range: -40°C ~ 60°C |
Control | Control the work of DC fan based on indoor and outdoor temperature. |
Monitor | Immersion Frequency of fan |
Alarm | LED display 4 alarm codes When it has immersion or frequency of fan is too low output alarm signal. |
Communication | Supply monitor software (installed in PC), use RS485 interface. |
Technical parameter: | |
Rating voltage | DC +42V~DC +57V |
Work ambient temperature | -25°C~+55°C |
Work ambient humidity | 5%~95%RH |
Temperature detect range | -20°C~+60°C, compensation can be reset via button |
Temperature accuracy | ±2°C |
Temperature resolution | 1°C |
DC fan on temperature | 20°C~40°C, set via button |
Return difference of temperature | 2°C~ 10°C, set via button |
Communication address | 1 ~ 99 |
DC fan control logic: | |
On | 1)Indoor temperature > preset of ‘on temperature’ 2)Indoor temperature – outdoor temperature > 5°C |
Off | 1)Indoor temperature < preset of ‘on temperature’ – preset of ‘return difference of temperature’ 2)indoor temperature ≤ outdoor temperature |
When outdoor temperature sensor has fault, controller control the work of DC fan based on indoor temperature. When indoor temperature sensor has fault, controller on the DC fan always work. | |
