How to connect the Comfort Control Panel
You will need: the appliance disconnected from the electricity supply
1. The Comfort Control Panel’s power cord must be type tipo FG7 3Gx2.5mm 2 . the power supply is 230V AC 1N 50Hz.
2. Cut a suitable length of cable.
3. The cable must be connected to the terminal block on the bottom right of the Comfort Control Panel. First make a hole in the
electrical cabinet near to the terminal block and pass the cable through it.
4. Connect the cable to the terminal block as given in Figure 6.7 p. 35 and fit a 10 A thermal cut out upstream of the Comfort
Control Panel.
How to connect the plant water circulation pump
Before making the electrical connections, make sure that work is not carried out on live elements.
To optimise the operation of the appliance install, on the primary circuit, variable rate WILO STRATOS PARA pumps, which are con-
trolled and modulated with the Mod10 controller.
No other models pump are supported.
The instruction for connecting the WILO STRATOS PARA pumps are given below.
Each WILO pump includes its power cord and signal cable 0-10V (both 1.5 m long) for connection to the appliance’s electrical panel.
For longer cable runs, use a shielded 2x0.75 mm 2 0-10V signal cable and a FG7 3Gx2.5mm 2 power cord.
You will need: the appliance in its permanent location.
1. Check that power supply is off.
2. Remove the front panel of the appliance and the cover of the electrical panel.
3. Connect the brown wire of the WILO STRATOS PARA pump on the terminal - of the connector HPMP on the Mod10 board. Con-
nect the white wire of the WILO STRATOS PARA pump on the te of the connector HPMP on the Mod10 board. Insulated
black and blue wires (see Figure 6.15 p. 43).
4. Connect the pump to the mains with an upstream external bipolar switch (see detail IP, Figure 6.15 p. 43) with a delayed
action 2 A fuse, or connect it to the terminal clamps inside the units electrical enclosure (see detail MA, Figure 6.16 p. 44).
5. After finished with all the above operations, close the electrical panel and refit the front panel of the appliance.
NEVER switch on or off the WILO STRATOS PARA pump through the switch on the power supply.
