INSTALLATION/OPERATION
OPERATING INSTRUCTIONS
The Remote Keypad Unit (RKU) is a portable, hand
held accessory for use with the York Variable Speed
Oil Pump Drive (VSOP). When connected to a VSOP
Drive it provides the ability to view the different con-
trols within the VSOP Drive. Typically, the RKU will
be used to determine what condition is causing the VSOP
Drive to fault. The RKU is powered by a 9 volt alkaline
battery (supplied). Auto Power-Down and backlight con-
trol features conserve battery life by automatically turn-
ing the RKU off after a specified time period and by
allowing selected use of the display backlight.
The Remote Keypad Unit has the abil-
ity to program many different controls
within the VSOP Drive. DO NOT
change any of these controls, they are
programmed at the factory and do not
require any adjustment. Problems as-
sociated with modifying any of these
controls WILL NOT be covered by war-
ranty.
