basic progaming questions

[NP_Reef]

hows this look so far for basic programing?

refuglight - (3-1)
Fallback OFF
Set OFF
If Time 24:00 to 08:00 Then ON
If Temp > 82.0 Then OFF
Min Time 030:00 Then OFF

heater -(3-2)
Fallback OFF
If Temp < 77.0 Then ON
If Temp > 78.0 Then OFF

heater2 - (3-3)
Fallback OFF
If Temp < 77.0 Then ON
If Temp > 78.0 Then OFF

chiller - (3-4)
Fallback OFF
If Temp > 82.0 Then ON
If Temp < 81.0 Then OFF


just wanting to make sure ive got this right before i move on to more advanced programing.

thanks.

You may want to reconsider your fallback statement on your heater and chiller if they have their own thermostats. Best practice is to set those a degree higher/lower than the Apex and leave fallback ON. That way, if your controller fails, you still have power to those outlets and the device thermostats will protect your tank until you can get things going again.

Also, I'm not sure 24:00 is valid. Try it but if it doesn't work right, change it to 00:00.

How large are your heaters? Since you have them running at the same temperature, if the combined power is less than 600W, you can run them from a single outlet. Outlets 1-3 and 5-7 are rated at 5A. Not a big deal, but it will save you an outlet for future use.

heaters are 300w each can they be on the same outlet?

so if i want my heaters to be on between 77* and 78*, and my chiller between 81* and 82* would it be better if they were set up like:

HEATER
Fallback ON
If Temp < 77.0 Then ON
If Temp > 79.0 Then OFF
with my heaters set at 78*

CHILLER
Fallback ON
If Temp > 83.0 Then ON
If Temp < 81.0 Then OFF
with my chiller set at 82*

thanks again, i appreciate the help.

You would set your heater for 80 in your above example otherwise you can't properly control it from the Apex. The same with your chiller. Set your heater 1 - 2 degrees ABOVE where you want your Apex to control and your chiller 1 - 2 degrees BELOW where you want your Apex to control. That way the Apex controls it but if the controller fails for some reason, your tank only goes 1 more degree before the built in thermostats take over.
