Alfa Electric Тример отпорник мал 25K CA9VK025

Manual instruction:

1. Start high temperature -cooling mode:when value of set starting value＞stopping temperature while detecting temperature ≥starting temperature,relay close and cooling equipment start working.When detecting temperature ≤ stopping temperature,relay disconnect and cooling equipment stop working.For example:Set starting temperature at 30℃，stopping temperature at 25℃，when detecting temperature value ≤25℃, relay disconnect and indicator lamp (blue)stop lighting.

2. Start low temperature-heating mode:when value of set starting temperature ＜stopping temperature,and detecting temperature ≤starting temperature,relay close and heating equipment start working. Detecting temperature ≥stopping temperature,relay disconnect and heating equipment stop working.For example,set starting temperature at 25℃,stop temperature at 30 ℃.while detecting temperature ≤25℃,relay close and start indicator lamp (red )lighting.When detecting temperature ≥30 ℃,relay disconnect and stop indicator lamp (green) lighting.

Start indicator lamp: Start(red) indicator lamp,means relay close and equipment start working.Stop indicator lamp: Stop(green)indicator lamp,means relay disconnect and equipment stop working.

Digital tube: Middle red digital tube displaying present detected temperature.

Left green digital tube is set starting temperature

Right green digital tube is set stopping temperature

Press keyboard START to set starting temperature

Press keyboard STOP to set stopping temperature.

1. Start high temperature-cooling mode, set starting temperature value＞stop temperature value,when testing temperature≥starting temperature,relay close and cooling equipment start working.When detecting temperature≤Stopping temperature,relay disconnect and cooling equipment stop work.For example:Set starting temperature at 30℃，stopping temperature at 25℃，when tested temperature ≤25℃,relay disconnecting and stop indicator lamp (blue) bright.

2.

Start low temperature,heating mode:set starting temperature ＜stop temperature,when detecting temperature ≤starting temperature，relay close and heating equipment start working

When detecting temperature ≥stopping temperature,relay disconnect and heating equipment stop working,For example:set temperature at 25℃,stop temperature at 30℃,when detecting temperature ≤25℃,relay close and indicator lamp (red) bright.
