4.5 ACTUAL WORKING TIME METER
• The unique feature measuring the actual working time of the heating element adds up the periods during which the device was using
nominal electric power (during standard operation the device regulates the temperature and uses very little power thanks to the
fact that it turns itself off for longer periods). It can be checked at any time how much electricity has been used, ie. during all day’s
operation. In practice it turns out to be up to a few dozens of percent less!
• 1. Meter reading: Press and hold the button — the display panel will show letter E followed by 4 digits separated by a hyphen
(actual operating time of the device), ie. E..0..2..-..1..5 means that the device was actually working for 2 hours and 15 minutes from the
last time the meter was zeroed.
• 2. Meter resetting: Press and hold the button until E 00-00 comes up.
Calculate the actual cost for energy consumption by multiplying the number on the meter by the nominal heating output (0,12 kW)
and the price of electricity (1 kWh).
4.6 ANTI-FREEZE MODE
• In case the device is off (switched off with button ) but remains connected to the mains and the ambient temperature falls below
6°C, the device will switch itself on to prevent heating agent in a towel warmer from freezing. The letters A and F flash alternately on
the display unit until the anti-freeze mode finishes, which is when the temperature rises above 6°C.
