introduction
The SMS-954 remote control unit enables you to control a heat pump from a remote location with the help
of ordinary text messages from a mobile phone. Switch between different modes and stay in full control
of the temperature in your home or weekend cottage. Avoid unpleasant surprises – be kept informed of
power failures or sudden drops in temperature so that you can counteract damage before the accident has
actually taken place.
Preparations
In order for SMS-954 to be operative, it must be equipped with a SIM card that is enabled at a mobile
network operator. For best results, start by using an ordinary mobile phone to check the local reception.
Please note that for the SIM card to work, its PIN code must be removed. This can be done by inserting
the card into an ordinary mobile phone. If you do not know how to remove the PIN code on your mobile
phone, consult the manual supplied with your mobile phone. The setting is usually found under ”Security
settings”. SMS-954 works with all mobile 2G and 3G network operators.
NB: Does not work with mobile network operators that only offer 3G network services.
Fitting the siM card
The SIM card holder is located under the service cover on the underside of the remote control. Note that
the remote control MUST NOT be connected to the mains power supply while the service cover is removed.
When the service cover is removed, the backup power supply to the remote control can be
switched off by setting the switch to the OFF position. Then you can locate the SIM card holder.
Unlock the SIM card holder by moving it backwards in the direction of the arrow (OPEN). Place
the SIM card in the track of the holder and move it forward again (LOCK). Then switch the backup
battery on again by setting the switch to the ON position. Place back the service cover.
nB:
If a “pay as you go” SIM card is used in SMS-954, it must be topped up with money.
Remember that a “pay as you go” SIM card normally becomes inactive if it is not topped up within
12 months.
