The Unifact Pro terminal unit controllers have been designed to meet most fan-coil heating/cooling applications. The controllers can be used as standalone devices or can be networked to an IC-Unifact for use in Satchwell Σ (Sigma) systems. The URC-41N-10X models include one relay for on/off fan control. The URC-51N-10X models include three relays for fan-speed control. Commissioning should require less than ten minutes. The required application can be easily selected and set up locally using the NCP Palm tool, which can run on a laptop computer or on a PC. Communications between NCP Palm and the controller can be via an infra-red/RS 232 link to the URC-IR-100, which connects to a socket on the end of the controller. The controller has three main modes: comfort (day), night (off) and economy. The controller can be switched into any of these three modes from the Satchwell Σ (Sigma) PC (if used). When used standalone, the controller can be switched between two modes: either comfort and economy, or comfort and night, as selected during commissioning. A voltage-free input (activated from, for example, a timer switch or PIR) is used to switch between the two modes. A second voltage-free digital input is available for connection to a thermostat, which enables automatic changeover between cooling and heating modes for 2-pipe fan coil unit (FCU) applications. A DU/DUS/DDU sensor can be used to measure temperature. A DUS sensor can be used to adjust the comfort setpoint. S-Link sensors can also be used to measure temperature and offset the comfort setpoint and to display the controller operation modes.

DI2 can also be used for all applications except the two-pipe FCU application as an additional controller mode input (which has the same effect as DI1 set with zero delay). DI2 is typically used for a time or window switch.
Notes: 1. The controller can be set up with a delay value applied to input DI1 to prevent a PIR or other occupancy sensor from continually switching the controller between modes during the day. 2. If the DI1 input is not required, no 0V link is required, since the input can be disabled from NCP Palm. 3. The controller can be configured to operate only in heating mode.
WIRING PRECAUTIONS
WARNINGS THIS DEVICE OPERATES AT 230Vac. LOCAL WIRING REGULATIONS AND USUAL SAFETY PRECAUTIONS MUST BE OBSERVED. DO NOT EXCEED RATED VOLTAGES. ALL RELAY OUTPUTS MUST USE A COMMON PHASE. DO NOT MIX PHASES. THIS IS REQUIRED TO PREVENT FLASHOVER BETWEEN DIFFERENT MAINS PHASES. ALL RELAY OUTPUTS MUST USE A COMMON VOLTAGE I.E. 230Vac OR 24Vac. DO NOT MIX VOLTAGES. THIS IS REQUIRED TO PREVENT THE POSSIBILITY OF FLASHOVER FROM 230Vac TO 24Vac. EXTERNAL RELAY(S) MUST BE USED TO SWITCH 24Vac WHEN THE COMMON VOLTAGE IS 230Vac. EXTERNAL RELAY(S) MUST BE USED TO SWITCH 230Vac WHEN THE COMMON VOLTAGE IS 24Vac. TO AVOID POSSIBLE CONTACT WITH MAINS VOLTAGES, WHEN WIRING IS COMPLETE, ENSURE THAT THE TERMINAL SHROUD IS CORRECTLY FITTED AND THAT THE MAINS AND RELAY TERMINALS ARE COVERED. Cautions Ensure that Terminal 13 (COM 0V) is securely connected to Earth. Do not route relay output wiring with any other controller wiring. Do not route triac output wiring with any other controller wiring. Do not route power and output wiring with signal wiring. Do not run Extra Low Voltage (24Vac or less) wiring in the same harness as mains wiring. The controller must be located as far away as possible (150mm minimum) from any contactors, switches and their associated cabling as they may cause interference when they operate. No connections can be made to the controller whilst ANY power is applied to it. This includes the relay outputs.
APPLICATIONS
IC UNIFACT FUNCTIONS
The following predefined control applications are available. For each application, fan-speed control is available with the URC-51N-10X models, and fan on/off control is available with the URC-41N-100. • Fan Coil Unit with Electric Heater and DX Cooling This is a simple fan coil unit application, with separate triac outputs for DX cooling and electric heater units, which are switched on or off based on the heating and cooling demand. • 2-Pipe Fan Coil Unit with Auto Changeover and Auxiliary Heater This uses a thermostat located in the water supply pipework to switch the controller between heating and cooling modes. The controller can be configured to operate in heating-only mode, if required. A triac output can be used to control an auxiliary heater to supply additional heat. • 4-Pipe Fan Coil Unit with Auxiliary Heater The 4-pipe FCU control application can control separate heating and cooling coils. A triac output can, if required, be used to control an auxiliary heater to supply additional heat if the heating coil cannot provide sufficient heat. • Air-Side Fan Coil Unit This application is for control of a modulating damper. The return air temperature is controller to the setpoint by altering the angle of the damper and therefore altering the bypass flow and the flow through the heating and cooling coils. In both comfort and economy mode, the fan speed is determined by the controller heating/cooling output.
Up to 80 Unifact Pro controllers can be networked to a single IC-Unifact in an Sigma network. The IC-Unifact enables several pre-programmed controller functions to be used, including the following: • Valve/fan exercise A signal from the IC-Unifact can be sent to controllers at a specified time to exercise the valves and fans. • Load shedding The IC-Unifact can limit the heating/cooling control output of a controller to a specified percentage of the maximum, based on the outside air temperature measured by a network sensor. In a simple 2-pipe system, for example, the valve position could be limited to 75% of its maximum. • Free cooling This is available if the fan coil has a fresh air inlet. The function enables a zone to be cooled by using fresh air that is at a lower temperature than the room temperature. The IC-Unifact receives the outside air temperature from a network sensor and, if appropriate, places the controller into free cooling mode. • Fire override Following a fire override signal from a Sigma front-end PC, the IC-Unifact forces the controller to stop the fan and all heating/cooling. • Summer/winter setpoint compensation The IC-Unifact receives the outside air temperature from a network sensor and can increase the controller’s comfort setpoint when the outside air temperature increases. This is based on the principle that the room temperature can be higher in summer, since people are using lighter clothing. • Temperature and fan speed updates The controller can receive temperature updates via the network or from a directly controlled sensor; also fan speed updates via the network.

Screened cable is required only for network (RS 485) connections. This screen must be earthed at one point only. At the UNIFACTPRO controller end, ensure that the screen runs continuously through to the next controller in the network. 3. The 15V output may also be used to power a PIR, where appropriate (30mA max.). 4. DDU uses terminals 9 & 12, DU uses terminals 9, 10 & 12, DUS uses terminals 9,10, 11 & 12.
