HI-LINE RC & HI-LINE RC Heater/Cooler 03

1.0 General Information

l This MYSON HI-LINE RC fan convector is designed for wall-mounted installation with a maximum installation height of 2.13m to the underside of the unit. l The minimum installation height is 1.8m to the underside of the unit.

l The minimum clearance between the top of the unit and the ceiling should be 50mm.

l The minimum side clearance is 100mm.

l The HI-LINE RC should only be used on closed circulation, two pipe, pump assisted central heating systems (HI-LINE) or heating and cooling systems (HI-LINE Heater/Cooler).

l Before proceeding with the installation, the heating system design must be considered and the unit correctly sized to meet the heat loss requirements of the room at normal fan speed. l This unit is supplied with an infra red remote control system and has 3 operating modes -

Automatic – the desired room temperature is programmed in to the unit and the fan speed is automatically adjusted until the desired room temperature is achieved.

Fan only – allows user selection of any of the 3 available fan speeds irrespective of room temperature or water temperature in the coil.

Fan only with water temperature control – allows the user to select any of the available fan speeds, which will operate only if the water temperature in the coil is above 32C. This enables control of the unit via an externally mounted room thermostat if desired.

l The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the appliance.

This unit MUST NOT be installed in a bathroom or other similar high humidity area.

2.0 Heating System Design

This fan convector must be fitted on a two pipe, pumped circulation heating system.

For optimum fan convector heating performance the system must be capable of providing sufficient hot water through the heat exchanger. This means that:

1. The minimum pipe size from boiler to fan convector must be 15mm.

2. This unit is not suitable for use on microbore pipework.

3. Where the unit is fitted on to a system with other emitters a separate circuit for the fan convector should be considered to provide adequate water flow.

4. The system water must be above 32°C for heating mode.

5. For heat pump applications - see Commissioning Procedure.

6. This unit is NOT suitable for one-pipe systems.

7. Optimum performance will require effective balancing of the whole system.

8. This unit should NOT be used to replace a radiator in an existing system unless an adequate flow of water can be guaranteed.

3.0 Unit Selection/Sizing

Heat output performance is given in the Technical Data section of this manual. Outputs are shown for the 3 fan speeds, however, it is important to size the unit to match the calculated heat loss requirements of the room with the unit operating on the low fan speed. The higher fan speeds are used in automatic mode when the room temperature is significantly lower than the preset temperature.

When establishing the temperature difference, ie mean water to room temperature, allowance should be made for temperature drop in the system. It is the water temperature at the unit which dictates the output.

4.0 Location

l This HI-LINE RC unit may be fitted to any convenient wall at a height from floor level that suits the application, providing an unimpeded flow of warm air into the area to be heated.

l The maximum distance from the underside of the unit to floor level is 2.13m.

l The minimum distance to the underside of the unit is 1.8m.

l This unit should not be installed in locations with ceiling heights greater than 3m.

l The unit should be mounted on a flat wall, and stud or partition walls should be avoided to minimise the possibility of noise transmission.

l For cooling applications, the need for disposal of condensate may influence the position of the unit.

5.0 Preparation

Before proceeding with the installation, unpack the carton contents and check against the checklist below:

1. HI-LINE RC fan convector.

2. 15mm isolating valves (1 pair).

3. Instruction manual.

4. Warranty card.

5. Fixing kit (rubber mounts and cable gland).

6. Remote control handset.

6.0 Fixing

l Using the fixing dimensions below (see fig. 1), mark the fixing hole positions on the wall. l Drill and plug the wall for No. 8 x 40mm round head wood screws ensuring that the wall plugs are suitable for the wall type.

l Remove the backing from two of the self-adhesive washers and place on two of the screws with adhesive side towards the point. l Tighten the screws into the top two fixing holes leaving about

9mm projecting. l Press adhesive washers to the wall.

l Remove the backing from the last self-adhesive washer and place centrally over the bottom fixing hole on the left hand side.

Remove the outer casing as follows: l Remove the 2 screws at each end of the outlet grille (see fig. 2).

l Lift off the outer case.

l Fit chassis on to the top two mounting screws and tighten.

l Secure the bottom fixing point with the remaining screw.

Note: Before proceeding with pipe-work connections check that the unit is level. If the right hand end is lower than the left then the ability to vent the unit may be restricted.

When water connections and electrical connections have been completed and the unit has been vented, fit the outer cover and secure with fixing screws.

9.0 Commissioning Procedure

(continued...)

Heat Pump and Low Water Temperature Systems

In heating mode, the control system brings the fan on when the water in the coil reaches 32°C. For low water temperature systems, eg heat pump systems, it is possible to switch off the boost speed option in automatic mode so that the unit runs in medium or normal fan speeds depending on demand. This means low outlet air temperatures from the unit are avoided when the room temperature is low in relation to the set temperature.

This facility can be switched on or off by following the instruction below l Isolate electrical supply.

l Remove outer cover.

l Change switch 1 position according to requirements

(see fig. 4).

l Refit outer cover.

l Switch on electrical supply.

The displayed temperature calibration function enables calibration in heating mode of the displayed temperature to the actual room temperature using the following procedure: l Press the On/Off key and + key simultaneously for 5 seconds.

The display will flash, alternating between ‘ro’ and the calibration temperature. l Calibrate the displayed temperature by using the + and – keys with the fan running.

l Press the On/Off key to finish.

Fan Pulse

Fan pulse mode causes room air to be drawn over the air temperature sensor periodically to maintain room temperatures more effectively. In certain circumstances, for example when units are over-sized in relation to the heat loss of the room, it may be necessary to turn off this function. Use dipswitch 3 according to requirements.

Displayed Temperature Calibration

Depending on the location of the unit there may be a difference between the temperature at the unit and the temperature in the middle of the room being treated.

HI-LINE RC & HI-LINE RC Heater/Cooler 09

11.0 Operating Instructions

Description

This HI-LINE unit is fitted with a control system that provides 3 different operating modes. In automatic mode the desired temperature set point is selected and the unit will adjust the fan speed according to the difference between the actual room temperature and the set point. When the room temperature reaches the set point the fan will switch off and thereafter will continue to cycle on and off to maintain the room temperature.

The temperature set point range is 15 - 35°C.

In manual mode the automatic temperature control is over ridden and any of the three fan speeds can be operated inrespective of the water temperature in the unit. This means that air circulation can be provided in summer for example, or that heating performance can be controlled manually.

In manual mode, with water temperature control, any of the 3 fan speeds can be selected and the fan will operate when the water temperature in the coil is greater than 32°C. This means that heating performance can be controlled manually, and the unit could be controlled via an external room thermostat.

The unit can be controlled using the infra red remote control handset supplied with the unit (see fig. 5) and also using the control panel on the unit (see fig. 6). If necessary, however, the control panel can be locked electronically to prevent tampering once the controls have been set (see over).
