Note:

 This equipment has been tested and found to comply with the limits 

for a Class A digital device, pursuant to part 15 of the FCC Rules. These 

limits are designed to provide reasonable protection against harmful 

interference in a residential installation. This equipment generates, uses 

and can radiate radio frequency energy and, if not installed and used in 

accordance with the instructions, may cause harmful interference to radio 

communications. However, there is no guarantee that interference will 

not occur in a particular installation. If this equipment does cause harmful 

interference to radio or television reception, which can be determined by 

turning the equipment off and on, the user is encouraged to try to correct 

the interference by one or more of the following measures:
• 

Reorient or relocate the receiving antenna.

• 

Increase the separation between the equipment and receiver.

• 

Connect the equipment into an outlet on a circuit different from that  

to which the receiver is connected.

• 

Consult the dealer or an experienced radio/TV technician for help.

18 - Features

This section describes the controller features for 1900e series of pumps. 

The controller is used for various remote control applications, including:

•  Remote on/off

•  Analog 0 - 10 V voltage control

•  Status relay feedback

There are several possible connection configurations. Not all functions can 

be used simultaneously.

•  on/off + 0 - 10 V + relay output
