HydroTOUCH Variable Speed Pump (VSD) Controller

Function Features

• Multi-pump Control - Control of up to 12 pumps in any number of duty, duty assist, and standby pump configurations.
• Pump Limiting - For limiting max flow or power requirements.
• Duty Sharing and Alternation - Adjustable duty change period and bumpless transfer.
• Pump Staging and Destaging - Additional pumps are staged into operation to maintain setpoint and destaged when no longer required.
• Staggered Pump Start and Stop - Prevents excessive current draw and reduces water surge or hammer.
• Manual Pump Control - Pump manual mode with ability to override system protections for 15 minutes before reverting back to auto mode.
• Control Directions –boosting or dropping pressure
• Pump Speed Control - Proportional speed control of pumps in level mode, PID speed control with adjustable proportional and integral values to change VSD responsiveness in pressure, flow, and temperature modes.
• Jacking Pump Control - Pump 1 can be configured as a DOL jacking pump or VSD static lead pump.
• Pressure Control Mode - Controlled by a 4-20mA pressure transducer and optional backup high-pressure switch.
• Pipe Fill - If the system wakes up and pressure is low, pipe fill runs a single pump to gently build pipe pressure and shuts the pump down if unable to build pressure within 10 minutes.
• Sleep Assist Speed Minimise - When the system is at setpoint and pump speed is constant due to no demand for water, the system will slowly drop the pump speed, helping it to go to sleep sooner
• Sleep Assist Boost - When the system is nearing setpoint, and there is no demand for water, the system will boost the pressure before going to sleep so it can sleep for longer, reducing pump cycling.
• Flow Control Mode - Controlled by a pulse flow meter, with optional backup high and low flow switches.

Enclosure
