The IR33 controller is the replacement for the IR32 range. It has all
of the functions of the IR32 plus additional features such as PID
control. All of the parameters on the IR33 have the same meaning
as on the IR32 so the IR33 will work in exactly the same way as
the IR32 if the same parameters are entered.
9 pre-set control modes
On/Off or PID autotune control
Selectable NTC, PTC or PT1000 sensor input options
1, 2 or 4 outputs relay or SSR drive outputs
Infra-red remote control and external key programming options
RS485 serial link for monitoring and programming
IP65 water and dust protection
Programmable advanced control options
