In automatic mode, a Sentera potentiometer with Modbus RTU communication
can be connected to RTVS1. To obtain demand based fan speed control, RTVS1
can be combined with a Sentera HVAC sensor. The combination of RTVS1
with a Sentera HVAC transmitter allows you to control fan speed in function
of temperature, relative humidity, carbon dioxide, air quality (TVOC) or carbon
monoxide. The controlled parameter can be selected in RTVS1 Modbus holding
register 20.
Crimp the RJ45 cable for the Modbus Master connector and plug it into the
socket. It is used to connect RTVS1 to a Sentera transmitter, intelligent sensor
or sensor controller. Consult our website for compatible devices
