Pola HP23 motorised valves positioner

General Discription

HP23 controls temperature by positioning equipment with a motor open and motor closed operation. eg. ventilation windows, gas valves, dampers, etc.

It comes with a thermister temperature sensor measuring in the range: -50.0/115.0 Deg.C or -58.0/239.0 Deg.F.

Variable on/off timed relay output and adjustable proportional band can be set for optimal opening and closing of motors with different speeds.

An added feature is the automatic recording of maximum and minimum temperatures for later viewing.

3 set points are programmable. Each set point is selectable by closing a pair of contacts at the rear with either a 100 Ohm resister, short cicuit, or open cicuit.

This enables easy change-over between common temperature settings.

The 3 position relay outputs are protected by a 3 Amp fuse
