Parallel connection of a number of thermic valve actuators to output Y1 using the UA1T
power amplifier.
The same principle applies to outputs Y2 … Y4. Note that the simultaneous load on
outputs Y1 … Y4 must not exceed 9.5 VA (power consumption at input X1 of the UA1T:
0.5 VA)

Y1 AC 24 V thermic valve actuator
Y1.1 AC 24 V thermic valve actuator (max. 2 STP72E actuators per Y1 output on the UA1T)
– The UA1T requires an AC 24 V supply voltage
– The UA1T is not suitable for the connection of 3-position actuators.
