8 / 123 Proline heating thermostat 02/2022
1.2 Other safety information
 Only connect equipment to PE grounded mains sockets.

At higher operating temperatures, parts of the bath cover can reach surface temperatures exceeding 70 °C. Be
careful when touching it

Risk of burning!

Use suitable hoses (

6.4).

Secure hose against slippage with the aid of hose clips. Avoid kinks in the hoses.

Check hoses from time to time for any possible material fatigue.

Thermal medium hoses and other hot parts must not come into contact with the mains cable.
 With the use of thermostats as circulating thermostats hot liquid can be emitted when the hose breaks, presenting a
hazard to persons and material.
 If no external load is connected, the pump outflow must be closed (use screw plugs) and the bypass valve must be
set to "internal" (

4.3).
 Take into account the thermal expansion of the heat transfer oils with increasing bath temperature.

Irritant vapors may develop, depending on the heat transfer liquid and operating mode used. Always ensure that the
vapors are adequately extracted. Use the bath cover.

When changing the heat transfer liquid from water to a thermal transfer medium for temperatures above 100 °C,
carefully remove all water residues, including from the hoses and loads. When doing this, also open the screw plugs
(HKN 065) (

3) of the pump outputs and inputs and blow compressed air through all the pump outputs and in-
puts . With higher temperature there is the risk of burning due to delay in boiling!
 Withdraw the mains plug before cleaning, maintenance or moving the thermostat.

Repairs in the control section must only be carried out by specialist personnel.
 Figures of temperature constancy and display accuracy apply under normal conditions according to DIN 12876.
Electromagnetic high frequency fields may in special cases lead to unfavourable values. Safety is not impaired.

The following action may start the thermostat unintentionally from the standby mode:
Previously activated timer mode (

"Start" command via interfaces (
