Dixell

Electronic Controllers

This booklet has been produced to assist you with the setting up and programming of Dixell

Controllers. It is not designed to totally replace the manufacturer’s manual, but rather to

compliment it. Please refer to the manufacturer’s manual when in any doubt.

The complete range of Dixell Controllers is extremely large, so only the popular models are

covered here. However, the method of programming any Dixell controller is very similar across

all the range.

Model numbers ending with “C” are 32 x 74mm panel mount versions.

Model numbers ending with “D” are DIN Rail mount versions.

XR = Refrigeration

Models beginning with “XR” are multi-function refrigeration controllers, most have defrost

interval timers, but some have Real Time Clocks for defrost. Dixell XR100 & 500 Series always

use PTC probes, Dixell Prime Series can use either PTC or NTC (selectable by parameter)

XT = Temperature

Models beginning with “XT” are for heating or cooling applications and can be programmed for

either function. XT120C & XT121C are two stage, but can be programmed to operate as Dead

Band controllers. XT130 & XT131C are Dead Band only controllers. XT models can accept a

range of probes but the type must be specified at time of order. They are most commonly, PTC,

Thermocouples K, J, S, Pt100, Ni100. Other input types are 0 to 1v, 0 to 10v and 4 to 20mA.

XC = Step Control

Models beginning with “XC” are step controllers. They can be used to control multiple stages,

compressors, condenser fans, heaters or pumps. They can work with a 4 to 20 mA input from a

pressure transducer or an input from a PTC temperature probe. This input type must be specified

at time of order.
