Switch off or set the temperatures of one or more receiver heaters.

Arguments:

Receivers ant

The set of receivers whose heaters are to be controlled.

Heaters heaters

The heaters to be controlled. This is a set of one or more of:

• cryo - The heater in the cryogenic part of the receiver.
• ambient0 - The first of two ambient temperature heaters.
• ambient1 - The second of two ambient temperature heaters.
• all - All of the above heaters.

HeaterVoltage volts

The voltage of the heater between 0 and 10, or the word: off.

Example:

The following example turns off both ambient heaters in receivers 3 and 4.

 heater rx3+rx4, ambient0+ambient1, off

Example 2:

The following example sets the target sensor voltages of the two ambient temperature controllers to 3.1v.

 heater rx3, ambient0+ambient1, 3.1

Context:

On power-up the heaters in each receiver are switched off. If they are needed, then they must be turned on and given a target temperature using this command. At the time of writing, none of these heaters are actually used.
