    11.0 INSTALLABLE OPTIONS 11.1 HEATER Bray offers an optional heater as a factory installable option for the Series 71 actuator to prevent condensation from forming inside the actuator. Units with On/Off actuation use a positive temperature coefficient (PTC) style heater which has a unique temperature – resistance characteristic. The heater self-regulates by increasing its electrical resistance relative to the internal temperature.
