8. advantage is that there is no need to install new telephone lines or other broadband connections just install the modem and an antenna The drawbacks are that the connection is slow and the computer you are connec ting from also needs modem 10 1 Prerequisites As an accessory to the heat pump the recommended GSM GPRS modem is available including special installation instructions Other modems can be used including ordinary telephone modems but there is no support available for modems other than the one recommended A SIM card for a subscription that should include GPRS access to an SMTP ser ver without authentication and a data phone number for dial up access The PIN code for the SIM card must be disabled 10 2 Settings in the WM HPC When using a modem you can still browse to the WM HPC from a local net work on site through the Ethernet port provided that the network setting for the gateway is set to 0 0 0 0 The DNS setting should also be 0 0 0 0 The next step is to change the settings under the Modem PPP tab under the menu SYSTEM SETTINGS The settings there are partly dependent on the mo dem and subscription used Check the instructions in the modem package The phone number for the Internet provider modem pool is the most important setting that must be set When an alarm e mail is to be sent from the svstem it dials this number to gain Internet access Under the Login tab vou can set the username and password for
