L BAL E234 GB MANUAL

9.7 Timer
9.7.1 Timerfunction
The device has a real time clock. The clock is backed up (Gold Cap) and has a reserve of 2 or 3 days
after sufficient operation on a voltage supply.
The time and date must be set during start-up operation and when using the real-time clock. The
device calculates the weekday based on the date.
In principle, the timer function acts like a digital switch input (timer “On”
closed contact at inverting
OFF). The same functions can be assigned to the timer switch as the digital inputs(“D1 ..D2)”.
Function Description * Timer ON =
(@ Timer Invert. = OFF)
OFF no function (factory setting)
Enable
(1D)
Enable (remote control) “ON” / “OFF”

Limit
(3D)
“Limit” ON / OFF
Influences control circuit 1 and control circuit 2 in operation
with two control circuits
Limit ON
E1 / E2
(4D)
Switch over input “E1” / “E2” (for operation with one control
circuit)
Signal at E2
Reset
(10D)

(11D)
Setting Max. Speed “ON” / “OFF”
Influences the respectively set value “1. Max. Speed” and “2.
Max. Speed” in operation with two control circuits.
Max. Speed ON

Switch over “Intern” / “Extern”
Possible only for operation with one control circuit!
Setpoint External
Control/Manual
(7D)
Switch over “automatic control” / “Speed manual”
Possible only for operation with one control circuit!

(8D)
Switch over control function (e.g. “heating” / “cooling”)
Reversal standard
1.Setp+Pband1/2
(15D)
for control circuit 1: Switch over Setpoint 1/2 and Pband 1/1
When programming this function, “Setting” additionally lists
the parameter: “1.Pband2 for control circuit 1.”
First control circuit Set-
point 2 + Pband 2
Only active in operation with a second control circuit
E1 / E2
(4D)
The output for control circuit 2 is additionally set to “A2” to
“A1” (regardless of the programmed function for “ A1”). The
first control circuit has no output for the duration of the switch
over.
The switch over input “E1” / “E2” as in operation with one
control circuit is no longer possible.
Second control circuit to
A1 + A2
