*1.An End Unit is always required for connection to a Basic Unit or an HFU. An HFU cannot operate without a Basic Unit. External communications cannot be performed when using a Basic Unit only.

*2.For heating/cooling control applications, control outputs 3 and 4 on the 2-point models are used for the cooling or heating control outputs.
On the 4-point models, heating/cooling control is performed for the two input points.

*3.When using the heater burnout alarm, purchase a Current Transformer (E54-CT1 or E54-CT3) separately.

Functional Upgrades
