GSMMOD
By connecting the modem to the S203 you can communicate with
SMS’s to the controller and have information of activated alarms to
GSM phone.
Ouman’s GSM modem is connected to the S203 unit or to M-LINK
adapter. The modem has a fixed antenna that can be changed to an
external antenna with a 2,5m cord (optional equipment) if needed.
The modem’s indicator light shows what mode it is in.
Inserting the SIM card
Press the small black SIM card release button with, for example, a
pen tip. Part of the SIM card slot will stick out of the modem. Pull the
slot out of the modem. Do not pull the slot out of the modem without
pressing the SIM card release button first!
Insert SIM card into the slot and make sure it settles properly. Push
the slot back to its place. Set the SIM card PIN code as S203 device
PIN code. Make sure PIN inquiry is in use in the SIM card.

In floor heating solutions it is important to make sure that exessively
hot water which could damage structures or surfaces doesn’t ever
get into the network. A mechanical thermostat should be installed
on a supply water pipe which stops the circulation pump in case of
overheating. Set the thermostat at 40 ... 45 °C. Set the S203 regu-
lator’s maximum limit b35 ... +40 °C and the minimum limit
b20 … +25 °C.
