CU-3TESP+AUTO CONTROL (For CU and CU-LH)
In this mode the user can rotate between Manual Off, Manual Speed 1, Manual Speed 2, Manual
Speed 3 and Auto Settings. Manual speed is indicated by the speed and ’M’ symbol. The current
selection is replicated to Modbus Input Register 2 (User Fan Speed). When in Auto position, the TRI
shows rotating fan icon and ’A’ symbol. The current automatic fan speed status information is greyed
out.
If the Modbus Master writes the Automatic Speed (0,1,2,3) to Modbus Holding Register 5 and the TRI
is in Auto state, the automatic fan speed is displayed on the TRI.
If the BMS writes to the TRI’s Holding Register 4 and the TRI shows the required fan speed (Manual
0/1/2/3 or Auto).
SRI-71 (Analogue 0-10Vdc Output) MODELS
With SRI-71 models it is possible to send the current fan speed set by the user to the analogue
0-10vdc output (1-speed: 0=0%, 1=100%; 2-speed: 0=0%, 1=50%, 2=100%; 3-speed: 0=0%, 1=33%,
2=66%, 3=100%; 6-speed: 0=0%, 1=17%, 2=33%, 3=50%, 4=66%, 5=83%, 6=100%).
When in NIGHT mode, the fan speed is set to the Fan Speed Night parameter value. When returning
from night the speed goes to 100% if fan mode is set to any of the ’auto options’. If the fan mode is
configured for ’non-auto options’ then the fan speed returns to speed 1.
