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.
