Renfro is spot on....I went with the 608 because its rated for 15 amps.The relay ampacity is 10 amps, so if the heater is more than 10 amp draw (many/most are) then you need a high amperage contactor or a different controller.
Wattage and amperage are two different animals. Listen to Renfro.I did the math. To heat the grow room and out side room. 750 watts.
On the oil heater. You crank the thermostat. The other knob has three positions. 1500 watt, 900, 600.
I use number "2". 900. With the controller.
84° grow room temp.
10amps would be about 1200watts.Wattage and amperage are two different animals. Listen to Renfro.
Watts (P) = Amps (I) X Volts (E) easy to remember PIE.Wattage and amperage are two different animals. Listen to Renfro.
I guess so yeah... the heater has 2 elements... I usually only run 1 and I switched it to 2.... then the inkbird fried. Might have to try something elseIs the heater pulling more amps than the inkbird is rated for? That could melt the relay contacts causing them to stick closed/on.
Yeah... you can build in the leeway wither side of the target temp.... I.e. target = 25c, but allow 23 before you turn on. Or turn off at 27 for example... all 3 numbers you can customiseWith an inkbird and oil heater, how much play can you build into the cycles? Can you tell it you want it on at 79 and off at 82? Does it offer that much customizing?
Renfo... how would I use a 306t qnd not blow it up? Is there a way of connecting it to a contactor? Any suggestions?Is the heater pulling more amps than the inkbird is rated for? That could melt the relay contacts causing them to stick closed/on.
You can set the dead band small and it won't heat as much.I have the 308 non remote , and it hasn’t given me any issues . You have to set the values with in degrees of each other . You should have a fan or or something to cool so if it does shoot up passed desired temp .or watch how many degrees it goes over by and holds at before dropping and minus that from your current set temp . So this way when it shoots passed it’s actually sitting where you want . But you should have something to cool so they can ping pong each other between heating and cooling .
I love my 308 . That and the humidity one have been game changers for me . It’s been hands free minus dropping and rising temp and humidity for lights on and off cycles . Hopes this helps
