Example
Preselection of the speed start condition allows for defining the input value.
An analog signal can be used as start or stop signal.
The limit values for when the corresponding motor is to be switched on or off can
be set via setting values "[Start value x] On" and "[Start value x] Off".

8.4.13 "On" by outside temperature
At low outside temperatures, motors can be run continuously to control a pump to
e.g. prevent water from freezing in pipes.
This function is available in 1-speed and twin motors.
Note
The function can be enabled only if there is an outside temperature value
(Section 5.6 "Outside temperature").
You can disable the function by setting "Outside temp-dependent ON" to "---".
In twin motor operation, the motor with the current run priority is switched on.
If the outside temperature drops below the set limit value, the RMS705B switches
on the motor of the circulating pump. The motor is switched off when the outside
temperature exceeds the limit value by 2 K.
