SETTING A ZONE NUMBER
Press the SETUP key again and the LCD will display
the word ZONE. The factory default is 00. This number
can be used to identify each Z2000RT thermostat wired
to a Z2000 zone control panel or when used in multiple
stand-alone applications. Use the UP and DOWN keys
to assign a ZONE number from 00 to 99. (Figure 6)
SETTING THE HEATING LIMIT
Press the SETUP key again and the LCD will display
the heating limit. The factory default is 76° F. Press the
UP and DOWN keys to change the heating limit setting.
It is strongly recommended that the limit not be set
Above Thefactory default setting. (Figure 7)
SETTING THE COOLING LIMIT
Press the SETUP key again and the LCD will display
the cooling limit. The factory default is 68° F. Press
the UP keys to change the cooling
limit setting. It is
strongly recommended that the limit not be set below
the factory default setting. Refer to Figure 8.
SETTING THE ACTUATOR SPEED
Press the SETUP key again and the LCD will display
the actuator speed. The factory default is 90 seconds
which is the time it takes the actuator to drive the
damper blade fully open or fully closed. This is a critical
step in the Z2000RT setup since the thermostat can
be used with a variety of 24 Volt actuators. If you are
unsure of the actuator speed, place the actuator in the
fully closed position and then apply 24 Volts to common
and normally open. The time it takes to drive the damper
blade fully open equals the actuator speed setting.
(Figure 9)
SETTING THE MODBUS ADDRESS
Press the SETUP key again and the LCD will display
the Modbus communications address. The factory
default is 01. The Z2000RT has integrated Modbus
communications capability for remote monitoring
and control. For more information on Modus
Communications, contact Ruskin (Figure 10).
TEMPERATURE CALIBRATION OFFSET
Press the SETUP key again and the LCD will display
the temperature calibration offset as shown on
Figure 11. The factory default setting is 0. Typically,
it is not necessary to adjust the temperature calibration
offset as the Z2000RT has been factory calibrated.
If calibration is necessary, a high quality electronic
digital thermometer must be used. Place the
thermometer sensor probe next to the thermostat
sensor and allow five minutes before comparing
the temperature readings. Use the UP and
DOWN keys to adjust the temperature calibration.
The range is +/- 9° F.
