RT100 Control System - Functions
Switching on the Temperature Control Unit
Upon switching on the main switch, the message
OFF
appears in the
display. The RT100 control system is now ready for operation and is
switched on by pressing the
ON/OFF
button, or by the timer, through a
digital input or an interface.
Depending on the programming, the set-point and actual values, as well
as information on the operational state of the control system or the tem-
perature control unit are displayed.
Starting up for the first time / Commissioning
Filling with the heat transfer medium
After carrying out the checks on the consumer, connecting the hoses and
electrical connections, proceed as follows:
•
Switch on the main switch on the temperature control unit
•
Open the vent valve on the consumer, and also the shut-off valve
(if fitted)
•
Using a funnel, pour thermal oil slowly into the filling port, until
the red indicator lamp of the level control is switched off. After the
pump starts up, top up again with oil until the pressure displayed
on the pressure gauge stabilizes at a constant level. This proce-
dure ensures that all lines (both inside and outside the unit) are
filled with thermal oil (for the minimum oil level, see the "Techni-
cal Data" chapter in the Maintenance section). Regloplas rec-
ommends thermal oils Regloplas RO300 or Therminol 66 (see
"Accessories for Temperature Control Units" brochure). As a pre-
ventive precaution, Regloplas recommends the addition of sys-
tem cleaner SR80 (see "Regloplas Temperature Control Units"
brochure, SR80 data sheet)
•
Do not close the vent valve on the consumer until thermal oil is
flowing out of the consumer at a regular rate
•
Since fresh thermal oil for filling/topping up the system generally
contains moisture, action must be taken to remove this moisture
as an essential precaution (see chapter on "Procedure in the
event of water condensation")
•
Check the temperature control circuit for leaks
