Ray-Dot RVS-22HA Installation Manual - Features
FEATURES
The RVS-22HA is a powerful environmental controller that can manage two variable ventilation
stages and two on/off ventilation/mist/heater stages. The “room temperature” is the temperature
averaged from # 1 to 4 probe readings. A humidity probe may be used to lower the humidity
level by activating stage 1 or by deactivating the mist stage.
It is important to read both the RVS-22HA User’s Guide and the present Installation Guide. The
Installation Guide provides information on physical characteristics of the controller, mounting,
connections, probes, troubleshooting and technical specifications. The User’s Guide explains
the workings of the controller parameters.
