Ceiling fan program for APex

[badbones]

I have a ceiling fan in my fish room that I used to control by room temp. I have since added a Humidistat and it works great. I noticed the other nicght it was not on though. The room was below the set on temp, but humidity was at like 60%. Take in mind its raining now so thats the reason for the increase. here is my program and im a total novice so bear with me please lol

Fallback OFF
If SwitchA5 OPEN Then ON
If SwitchA5 CLOSED Then OFF
If RoomTem > 81.0 Then ON
If RoomTem < 79.0 Then OFF

its pretty basic and the humidistat is hooked to a break out box

I also have the humidistat set close to 40%

Thanks
Tony

Try this:

Fallback OFF
If SwitchA5 CLOSED Then OFF
If RoomTem < 79.0 Then OFF
If RoomTem > 81.0 Then ON
If SwitchA5 OPEN Then ON

This way, either high temp or high humidity will turn on the fan.

You can cut the program down to:

Fallback OFF
Set Off
If RoomTem > 81.0 Then ON
If SwitchA5 OPEN Then ON

I have something similar but I also turn the FANs on a bit each hour; in addition to humidity control. Watch the humidity stat; I noticed mine worked backwards; Open was high, closed was low.

cool thanks you two!!!

I will try yours Ken as I got the humidistat u remomended and you are correct about the reversing.
I now have a new question Ken..


With your program, will it keep turning on and off the fan as it goes above and below the set temp?


Thanks again!!

If it does, just add the following:

Min Time 10:00 Then OFF

This will keep it OFF for 10 minutes before it will be allowed to turn back ON.
