6. Notes on Batteries and Rechargeable Batteries
• Keep batteries/rechargeable batteries out of the reach of children.
• Ensure that the polarity is correct when inserting the batteries/rechargeable batteries
(observe plus/+ and minus/-).
• Do not leave any batteries/rechargeable batteries lying around openly. There is a risk of
batteries being swallowed by children or pets. If swallowed, consult a doctor immediately.
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin at
contact; therefore, use suitable protective gloves.
• Batteries/rechargeable batteries must not be short-circuited, disassembled or thrown into
fire. There is a danger of explosion!
• Do not recharge normal batteries. Danger of explosion! Only charge rechargeable batteries
which are intended for this purpose; use a suitable battery charger.
• Never mix batteries and rechargeable batteries.
• Do not mix batteries/rechargeable batteries with different condition (e.g. fully and partially
charged batteries). Always use two batteries/rechargeable batteries of the same type and
manufacturer for operating the room temperature controller.
The room thermostat may also be operated with rechargeable batteries. The lower
operating voltage of rechargeable batteries (batteries = 1.5 V/cell, rechargeable
batteries = 1.2 V/cell), however, will lead to a much shorter operating times.
For secure, long-term operation of the product, we therefore recommend using only
high-quality alkaline batteries and no rechargeable batteries.
If you still want to use rechargeable batteries, NiMH batteries with a low self-discharge
should be inserted in the room temperature controller.
