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). CU/CU-LH use Input Register 2
to read the user fan speed. If TRI is set to Auto, the CU uses the internal fan control logic to calculate
the required fan position.
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 CU/CU-LH 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 (future feature).
If the BMS writes to CU Modbus registers 40x30 the fan speed, this message is tunnelled to the TRI’s
Holding Register 4 and the TRI shows the required fan speed (Manual 0/1/2/3 or Auto). In turn TRI
replicates this value to the Input Register 2 (User Fan Speed), and CU/CU-LH uses this setting for fan
control.
TRI-3A (Analogue 0-10Vdc Output) MODELS
With TRI-3A 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.
