Can I use re-chargeable batteries in my Wiser Radiator Thermostats and Wiser Room Thermostats?

We advise against the use of re-chargeable batteries in the Wiser system, and recommend only the use of standard AA batteries - non-rechargeable. This is due to the nature of re-chargeable batteries not being optimised for Wiser device system use. 

Most standard rechargeable batteries have a lower starting voltage than conventional disposable batteries,  which  means the Wiser Radiator Thermostat will not get the voltage required to drive the motor as designed, leading to a system potentially behaving at sub-optimal levels.
