単純に値のマッピングだけのインポートはできなかったかと思いま
す。

「管理」->「一般設定」で右上のプルダウンから「値のマッピング」
を選択して登録することになると思います。

名前と値のマッピングは、以下のようになります。(Zabbix 2.2.9)

Zabbix 2.4.5では、「Maintenance status」という名前のマッピン
グが追加されています。
追加分だけを抜き出すと以下のようなイメージです。

| Maintenance status | 0 | normal |
| Maintenance status | 1 | in maintenance |
| Maintenance status | 2 | no data collection |
