Because of the many variations found in heating system piping layouts, Honeywell Braukmann offers a complete selection of control types and valve body patterns.
Some control operators have the sensor built-in.
This type of control can only be used where enough free space exists around the valve body to allow adequate air flow past the sensor. Built-in sensor type controls must be installed in a horizontal position, to prevent rising air warmed by the hot valve body from influencing the sensor. Control operators with external sensors can be installed in any position. The separate sensor can easily be mounted in a position to measure and control the room air temperature. These controls are thermostats -with sensors that measure the air temperature in their immediate vicinity.
