The UMC controller is an feature packed underfloor manifold controller. Designed to be compact for ever decreasing panel space but have features that improve the design of the installation.
Auto Pump / Boiler
The UMC automatically controls the AC output which can be used for a local manifold pump or wired back to triger a boiler. This feature is default, however, the AC output can be switched to a manual mode which allows full control over it via the Modbus interface and specific register.
Temperature Probe Inputs
THe UMC has three 10K3 probe inputs that can be used to feed temperature information back the the BMS / Home Automation system. These could be pipe sensors, external temperature or other rooms that don't have a dedicated thermostat.
Dual Fuse Actuators
The actuator head have two fuses so an fault will only effect four of the eight actator outputs. The fuse head are simple to access even when the product is installed with a cabinet full of cabling.
Fail Safe Supply
The UMC can be attached to two different power sources to provide a fault level protection. The supply for the actuator heads can be supplied by a seperate power supply to that that powers the units control system. This way if the actuator heads develop a fault and trip the supply the UMC will remain in comuncations with the BMS control system and retain its digital inputs and temperature sensor feedback.
