Ray-Dot RVS-22HA Installation Manual - page 2
DO NOT SPRAY WATER ON THE CONTROLLER.
The room temperature where the controller is located MUST ALWAYS REMAIN
BETWEEN 32° AND 104°F (0° AND 40°C).
To avoid exposing the controller to harmful gases or excessive humidity, it is
preferable to install it in a corridor.
Inputs and outputs circuitry is protected against overload and overvoltage. However,
we recommend installing an additional protection device on the supply circuit as well
as an external relay on all ON-OFF stages to prolong the life of the controller.
We strongly recommend connecting the controller to an alarm system, and installing
a supplementary natural ventilation system as well as a back-up thermostat on at
least one cooling stage. Refer to the wiring diagram enclosed with this installation
guide to connect the thermostat.
