Best way to control two heaters?

Hi, I have two Shego titanium heaters (no built in thermostat) - can anyone tell me the best way to set these up to maintain 26C? I have read a post regarding using one set as "Heater" and the other set as "Bottom Heater", is this the correct way to set them up? Both heaters will be in the sump, where the temp probe is located. Regards, Andy

Please have a look into the user manual of ProfiLux:

1.3.1 How do I set the temperature control?
1. Setting of the function: Set the required nominal value, see 2.1 Nominal value.
2. Setting of the hardware: Set which switchable output (socket) is responsible for switching themain heater,
the ground heater and the cooling (if existing), see 8.3 Switching output.

In chapter 2.1 "Nominal value" the interaction between heater and bottom heater is described.

Thankyou Carolin, as I understand it, the "Heater" is only switched on if the "Bottom Heater" is not sufficient, so should I assign Socket 1 to "Temperature 1" & "Substrate Heater" and Socket 2 to "Temperature 1" and "Heater" - so no need for a Virtual probe? Thanks, Andy

Yes, correct.
