- Page 10 We suggest carrying out the control unit LED test regularly. For this operation, press the TEST key briefly; all the displays turn on for 2 seconds. If one of the LEDS does not work, please return the control unit to TECSYSTEM for repair. ALARM RELAY TEST This function allows you to carry out a test of the relays operation without having to use further devices.

Note: image relay contacts in non-alarm condition, except for the FAULT relay which switches: contacts 10–11 closed (NO) contacts 9-11 open (NO) fault condition identification.
- Page 16 POWER SUPPLY The FO 935 ETH can be supplied by 85 to 260 Vac-Vdc, 50/60 Hz irrespectively of polarity in Vdc (terminals 40 - 42). This particularity is obtained thanks to the use of a tested power supply, of new conception and realisation, which frees the installer from any uncertainty regarding the correct Vac or Vdc power supply.

Page 20: Programming Notes
We recommend you check the device's programming before starting the device. The default parameters set by TECSYSTEM might not match your requirements. Programming the device is the end user's responsibility. The settings of the alarm thresholds and enabling of the functions described in this manual must be checked (by a specialist engineer) according to the application and features of the system the control unit is installed on. -
Page 21: Introduction To The Ethernet Module
The ETH module is always in slave mode. The FO 935 ETH control unit is in communication with the network only when it is in temperature reading mode, while it is inactive when in the following modes: display, programming and test relays. -

Trip thresholds and that the Fan-on thresholds must be higher than the Fan-off thresholds. In case you try to set these thresholds incorrectly, the control unit FO 935 ETH will not proceed with the programming and storage of data, therefore in subsequent readings will read the data from the previous schedule. -
