Tips for Setting Time Delay

Depending on the function selected, not every time delay is possible with this unit.  For example, time delays of 12.55 Seconds or 145.5 Minutes are not valid settings for Single Mode functions.  The Dual Mode functions are even more limited due to the fact that five switches are used for time t1 and 5 switches are used for time t2. 

Use the following tables to determine what time delays are valid.  If you cannot set the exact delay you want, then find one as close as possible.  For example, if you want a delay of 12.55 Seconds for a Single Mode function, which is not valid, select 12.5 Seconds or 12.6 Seconds.  If you need a t1 or t2 delay of 40 Seconds for a Dual Mode function, which is not valid, the best option is to select 0.7 Minutes or 42 Seconds.
