Description
Numeric
Keypad
The above figure shows the SETPOINT screen with WATER setpoints selected. The various setpoint
groups are in a column on the right side of the screen. Each button contains a number of setpoints
grouped together by similar content. The WATER button (as shown) contains various setpoints
relating to water temperatures. If either starter display option has been included, an additional button,
STARTER, will be located above the TIMERS button.
NOTE: Some setpoints that do not apply to a particular application may still be listed on the screen.
They will be inactive and can be ignored. For example, of setpoints 1, 2, and 3 above, only one will
be active depending on the unit mode selected in the MODE setpoints, 10 and 11 only for Templifiers.
The numbered buttons in the second from right column are pressed to select a particular setpoint. The
selected setpoint will appear in blue on the screen and a description of it (with the range of available
settings) will appear in the upper left-hand box.
