Averaging Slab Temperature
The slab sensor can only be connected to the Rs3 input on the 063. If you wish to
average slab temperatures, connect slab sensors in a series / parallel arrangement as
shown. The 063 will see one average slab temperature and respond accordingly.
Room or Slab Temperature Control using a Slab Sensor
The RTU 063 can be configured for slab and air temperature control using a slab sensor
connected to the Rs3 and Com terminals (3 & 5) and the air sensor in the RTU. The
control that the 063 is connected to must be configured to support this feature. The
minimum and maximum slab temperature and air temperature settings are adjusted at
the RTU.
If the air temperature sensor at the RTU is turned off, the air temperature is ignored.
