Herpstat 2 setting question

[searcyc1]

How do I make it so that when I adjust the temperatures the herpstat will gradually increase the temperatures not a max power instead of it using 100 percent power to reach the desired temperature? Thanks.

it will start out at max and then slowly taper off once it gets closer to the target temp. I'm not sure if there is any way to set the power like the way you are describing.

Why do you want it to do that way?

Because if it is applying max power the flexwatt could get to hot for the ball python?

That is the point of the thermostat. Once the thermostat detects that the flexwatt is getting close to the desired temperature, it will slowly start to cut the power until it levels out at the desired temp. It doesn't get super hot right away, it takes some time for it to warm up. The herpstat is smart, it won't ever heat up too much and then cut the power. It starts out strong, but tapers once it gets close to avoid over heating.

That's why you don't put your ball in the enclosure until the temps have settled.

You do not need to. It is automatic with the hew herpstats they all have 'soft heat' applying 1% power per cycle so it takes a bit of time to to hit full power. The new units all have this as a fixed setting.

The reason I'm concerned is because it shows 100 percent power until it gets close to my desired temp then runs around 60-70 percent. Then it typically will cut all power to 0 percent for a few seconds when the probe goes over set temp then goes back to 60-70 percent . I just assumed the heat tape got hotter than the set temp when it is being powered at 100 percent to get the probe to read the desired temperature. In other words I view 100 percent as the same as plugging the flexwatt directly into the wall.

It is...until it reaches the desired temperature. No need to worry about this.

Its not like the flexwatt immediately reaches 130* when plugged straight into the wall. It takes some time to reach that temp. The thermostat will dim the power down (as you witnessed) when it approaches the target temp. Then it will reduce the power to keep it at the desired temp. You might see it go back up from time to time if the temp falls lower than the target.

I understand the concern it is a feature that cannot be turned off. From cold it simply will not apply max power it slowly ramps the power up. Once running it will apply the power needed to hold the element face at exactly the correct temp. It is proportional, it does not turn on and off it either cycles on/off many times a second (pulse) or it changes the amount of power (dimming) to hold the probe at the same temp. It sounds like you do not grasp the nature of proportional. The soft heat system you have describes is only from cold where the other proportional units apply max power until the probe warms up. The herpstats does not. Reducing a cool probe spike.
