VL	Three-phase fan magnetothermal switch
PM	Cooling pump protection/control
EPAL	Heating and alarm control extension for TE/66 series
WT1s	Psichrometric kit for humidity

Choice of Power Unit:
To select the correct model size, you need to calculate total input value of the load to be controlled by adding the various input values together (power modules are classified in Amperes - see table on last page).
NB: The input values for fans can be added together normally. In the case of several single-phase pumps, as each pump is loaded on a single phase, remember to from 1 to 3 pumps you only add the current of one pump, from 4 to 6 pumps you add the current of two pumps, and so on.
E.g., in the case of four 230V 3A pumps, the load to calculate is 6A (two pumps on one phase and one on the other phases).
In the case of three-phase pumps, add the current as for fans.
As well as the amperage, also specify voltage and line frequency, which depends on the type of the local electricity supplied.

Choice of Control Module:
After calculating the power supply, you can choose between four different types of operational modes:
/11 Series (Module HP11): one ventilation group
/12 Series (Module HP12): two ventilation groups.
/57 Series (Module HP57): one ventilation group + cooling
/66 Series (Module HP66): four fan groups + heat+cooling+alarm

Refer to the data sheet opposite for further details.

Choice of options:
The equipment selected must be equipped with magnetothermal switches mounted on the power part and various options.

N.B: When ordering, specify the rated current of the fans and pumps so that the equipment can be supplied with the right thermal protection settings.
* For /66 models, the humidity probe (WT1s) and COOL-ALARM outputs (EPAL) are not included in the price.
For other models, these optionals have to be ordered separately.

Sample order:
For controlling six 400V HP 1 fans (I=1,9A) and two pumps 230V HP0,5 (I=3A), the power unit will be the TE16 [(6x1,9A) + (1x3A)] = 14,4A type.
Supposing you wish to control a four-unit system, with the pumps starting on the last unit, you need type /66 control so the product code is TE16/66.
If you add the the optionals (magnetothermical switch), the full code is TE16/66+6VL+2PMS+EPAL+WT1s
The price is calculated as follows:TE16/66+6VL+2PMS+EPAL+WT1s = (See table on prices list).

The models TE10/11-TE16/11-TE10/12 are mounted in plastic box, and in the case of PMS option (single-phase circuit breaker for the pump) the switch is accessible within the framework, while all other options are accessible from the outside. All other models are mounted in metal box with door transparent.
