Digital output configuration (1d, 2d)
Settings for PWM outputs (1d00 / 2d00 = OFF, 1d05 / 2d05 > 0), 1d = DO1, 2d = DO2
Parameter Description
Range
Default
1d 00
Enable digital/PWM or floating point (3-point valve) output
OFF= DO1 and DO2 are two digital/PWM outputs
ON = DO1 and DO2 are one floating point output (DO1 open, DO2 close)
ON/OFF
OFF
1d 01
Select control loop or special function (0= OFF)
1= LP1, 2= LP2
3= Dehumidify (4 pipe, max LP1 cooling, LP2 direct)
4= Manual positioning (on/off)
5= State functions

When 1d01 = 1, configure output:
0= Stage 1 heating/reverse
1= Stage 1 cooling/direct
2= Stage 1 heating and cooling, reverse and direct
3= Stage 2 heating/reverse
4= Stage 2 cooling/direct
5= Stage 2 heating and cooling, reverse and direct
If 1d01 = 4 Manual positioning or time schedule controlled
0= Time schedule controlled only
1= Manual positioning and time schedule controlled
When 1d01 = 5, select state functions:
0= ON if controller operation state is ON
1= ON while demand on any output
2= ON while controller in heating mode and operation state ON
3= ON while controller in cooling mode and operation state ON

➔
Low and high limit alarms are defined with input parameters. With output parameters assign
an alarm to an output and select output state. Each alarm’s required output can be
individually selected. Multiple alarms can be signed to one output. Should one alarm be
simultaneously selected to activate and deactivate the output, the one to de-activate has
precedence.
➔
With manual positioning (1d01=4) position the output directly (ON/OFF).
➔
With dehumidifying (1d01=3) the maximum value is taken of cooling and dehumidifying. When the humidity is too
high, cooling will continue to operate, even without a demand for cooling, to dehumidify the air and heating will
activate to maintain comfort.
➔
State functions (1d01=5) activate the output based on certain conditions with or without a demand for heating or
cooling, in either occupied (comfort) or unoccupied (standby) mode. In Energy Hold OFF mode (EHO) the output will
be off.
➔
Pulse width modulation (PWM) mode is enabled with 1d05. In PWM mode the digital output will be switched on/off
once per cycle. The on and off times are calculated according to the PI settings of the respective control sequence
(see control loop Parameters L09
–
L15, page 13). TCI-W11-U and TCI-W22-U use relays for the digital outputs.
Important Note!
If you enable PWM function, the meaning of parameter 1d03/2d03 and 1d04/2d04 changes to duty cycle
limits!
Make sure the values of 1d03/2d03 and 1d04/2d04 are set correctly!
Recommended default: 1d03/2d03 = 0%, 1d04/2d04 = 100%.
It is not recommended to use cycle times below 100 seconds as the lifetime of the relays will be shortened
with frequent switching. For PWM applications requiring cycle times below 100 seconds we recommend
using TCY-FT with TRIAC outputs.
1) The PWM duty cycle signal is not spanned between the min and max settings. It is just cut off. Any output
percentage below the min will be fixed at the minimum time. Any output percentage above the maximum will be fixed
to the output maximum.
