When setting the filter clean reminder function, timer zone will display 2 digits, of which the former
indicates the pollution degree of operating place and the latter indicates the accumulated operating time of
indoor unit. There are 4 types of situations:
(1). &OHDQ5HPLQGHULVRII7LPHU]RQHVKRZV³³
(2). Slight pollution: the former digit in timer zone shows 1 while the latter one shows 0, which indicates the
accumulated operating time is 5500hr. Each time the latter digit increases 1, the accumulated operating time
increases 500hr. When it reaches 9, it means the accumulated operating time is 10000hr;
(3). Medium pollution: the former digit in timer zone shows 2 while the latter one shows 0, which indicates the
accumulated operating time is 1400hr. Each time the latter digit increases 1, the accumulated operating time
increases 400hr. When it reaches 9, it means the accumulated operating time is 5000hr;
(4). Heavy pollution: the former digit in timer zone shows 3 while the latter one shows 0, which indicates the
accumulated operating time is 100hr. Each time the latter digit increases 1, the accumulated operating time
increases 100hr. When it reaches 9, it means the accumulated operating time is 1000hr;
The detailed pollution level and the corresponding time is as shown in Table 2-4-1 below:
