There are five temperature sensors (T1, TA, T2A, T2, and T2B) and five extension wires in the accessories, as shown in Figure 4.3a.
4.3 Temperature sensor Installation
fig.4.3a
fig.4.3b
Mounting location for temperature sensors:
T1:
is an AHU inlet air temperature sensor; it should be installed at the air inlet of the AHU.
T2A:
is an AHU evaporator inlet temperature sensor; it should be installed at the inlet pipe of the evaporator.
T2:
is an AHU evaporator intermediate temperature sensor; it should be installed at the intermediate pipe of the evaporator.
T2B:
is an AHU evaporator outlet sensor; it should be installed at the outlet pipe of the evaporator.
TA:
is an outlet air temperature sensor and therefore does not need to be installed if outlet air temperature control is not selected.
