1. INTRODUCTION

The control panel is designed for use with a single Reznor warm air unit heater. Thecontroller comprises of an electronic time clock, air sensing thermostat and frost protectionthermostat, a Heat/Vent/Off switch – giving ‘fan only’ operation on air heaters and ‘heatingoff’ facilities (except for frost protection for use during holidays etc.), LockoutIndication/Reset switch and a Clock override function.

Note : Lockout Indication/Reset optional connection for use with automatic ignition unitsonly.

4. SITING

4.1 Temperature Sensing

The selection of the correct position for the control panel is particularly important. The unitmust be fitted at a point, which will be generally representative of the heated area.Draughty areas, or areas subjected to direct heat (e.g from the sun, radiators, heateroutlets etc.) or areas where the air movement is relatively stagnant (e.g recesses) are allpositions to be avoided when siting the unit. Ideally, units should be mounted 1.5m fromthe floor.

5. INSTALLATION

IMPORTANT

The structure onto which the controller is mounted must be stable and vibration free.

5.1 Mounting

a) Remove the two cover securing screws on the front of the unit and swing open thedoor away from the base.

b) Offer the unit up to the intended mounting position and mark the location of the topkeyhole slots.

c) For fixing into wood, drill pilot hole to suit No. 8 screws. On masonary, drill hole(No.10) to accept the wall plugs. If the unit is to be fitted to metalwork, use a 5.5mmdrill.

d) Mount the base panel using No. 8 x 1¼” round-headed screws. On metalwork, useM5 machine nuts and bolts or similar.

e) Re-position unit and repeat for remaining two holes.

4

AMST1 GB EN 9711A

5.2 Electrical Connections

IMPORTANTWiring external to the unit must be installed in accordance with current I.E.E. Regulationsand any local regulations that apply. Wiring should be contained in conduit, entry for whichis provided on the top right of the enclosure.

Heat/Vent circuits are volt free. The use of the Summer Vent operation is optional andrequires a single wire from terminal 3 in the controller to the heater.

The use of the remote lockout reset (where applicable) is optional and requires a wire fromterminal 4 to the heater. This is a return neutral.

It is important to note that it is not acceptable to provide the main supply to the heater viathe controller. Complete the external wiring in not less than 1.5mm² cable.

NOTE: The mains supply to the controller should be taken from the heater.

CAUTION

a) Insulation test of site wiring must be carried out prior to making connections to aunit. Do not use a Megger once a unit is connected.

b) For continuity test, use only a low voltage instrument e.g Avonmeter set to OHMSrange.

6. DESCRIPTION AND METHOD OF OPERATION

6.1 Heat/Off/Vent

a) In HEAT position, the air heater(s) will operate under control of the time clock andthermostat.

b) In VENT position, the main fan of the heater will run continuously; the temperaturesensing control circuit being immobilised.

c) With the switch in the centre position the heating would be OFF except for frostprotection (for use during holidays etc).

6.2 Thermostats

a) Frost (night set-back) Thermostat

The frost (night set-back) thermostat should be set low (0°C - 5°C) and operatesoutside clock settings.

b) Day Thermostat

The day thermostat is set to the desired occupancy temperature and operatesduring clock settings.

5

AMST1 GB EN 9711A

7. SETTING OF DIGITAL TIME SWITCH

Fig. 2 Time Switch

7.1 General

The timer enables 8 ON and 8 OFF switch selections to be made automatically by settingthe day, time of day and selecting the ON and OFF periods required. Features include asoft override function and a permanent ON override or permanent OFF override functions.

7.2 Access to the Program Dial for Time Setting

To gain access to the program dial for time setting, remove the clear plastic cover by liftingoff.

7.3 Setting Day of Week and Time of Day (refer to Fig 2).

To prepare the module for programming, clear the memory by pressing the button marked‘R’. Slide the ‘RUN’ button to the left marked ‘ ’. Press the ‘Day’ button until the blacktriangle indicates the current day of the week. Use the ‘HR’ and ‘MIN’ buttons to set thehours and minutes to the actual time.

Rapid selection can be achieved by continuously holding down the HR or MIN buttons.Slide the ‘RUN’ button back to the centre position.

7.4 Planning a Program

A program is a pair of ON/OFF settings, which will dictate when the heater will switch ON orOFF. Up to 8 ON/OFF settings may be programmed. Odd numbers are program ‘ON’ andindicated by a ‘ ’, even numbers are program ‘OFF’.

Multiple days can be programmed by continuous depressing of the ‘DAY’ button. Thesesettings can be individual days, Monday to Friday, Monday to Saturday, Monday to Sundayor Saturday and Sunday only.

To program slide the ‘RUN’ button to the right marked ‘p’. Using the ‘DAY’ ‘HR’ and ‘MIN’buttons, set the first ON program. Depress the button ‘p’ (situated to the left of the daybutton) to confirm the setting and program 2 will appear. Set the OFF program time andday(s).

Continue until programs are complete. Slide the ‘RUN’ button back to the centre position(there is no need to go through all non-used programs). The clock settings and programsettings are not complete.

6

AMST1 GB EN 9711A

7.5 Manual Override

Under normal circumstances the ‘AUTO’ button will be the centre position. There are threefacilities for override.

1. CONSTANT ON Slide the auto button to the left indicated ‘I’. The air heater(s) will operate in a constant on state but de-

pendent on stat temperature.

2. CONSTANT OFF Slide the Auto button to the right indicated ‘O’. The air heaters will not operate unless in a frost condi-

tion.

3. SOFT OVERRIDE Depress button ‘ ’ at any time during a cycle. This willchange the current status to it’s opposite i.e. On to Off.

8. COMMISSIONING AND TESTING

NOTE

Ensure that all external electrical connections have been made and that a mains electricalsupply is provided to the unit.

8.1 Functional Tests

After setting the clock, carry out the following checks :

a) Ensure Heat/Vent switch is set to ‘HEAT’.

b) Set clock program constant override to position ’I’.

c) Turn Day thermostat control clockwise until ‘Heater On’ indicator lights. This willoccur once the thermostat setting exceeds the ambient space temperature.

d) Slide clock programming constant override to position ‘O’. ‘Heater ON’ indicatorextinguishers. Turn ‘Frost’ thermostat clockwise until ‘Heater ON’ indicator lights.Turn ‘Frost’ thermostat anti-clockwise until ‘Heater ON’ indicator extinguishes.

e) Slide clock program override to ‘AUTO’. Press soft override button marked ‘ ’.This will be displayed to LED. ‘Heater ON’ indicator lights. Turn the day thermostatto a low setting. ‘Heater ON’ indicator extinguishes. Press soft override button -‘ ’ disappears from LED.

f) Set ‘HEAT/VENT’ switch to ‘VENT’. Check that the heater fan operates but that theburner is not lit and that ‘Heater On’ indicator does not illuminate.

g) Adjust thermostats (and switch settings on clock) to clients’ requirements. Ensurethat any clock override(s) are re-set to appropriate position to suit program.

AMST1 GB EN 9711A

9. HANDING OVER TO THE USER

Explain the principles involved in setting up the time switch and demonstrate the operationof the unit.

9.1 Normal Automatic Operation

The clock should indicate the correct current time and day of the week. The ‘Heating ON’indicator will be illuminated when the thermostat is calling for heat and the clock switchingstatus is ‘ON’ (or in ‘constant ON’ or soft override ‘ON’).

9.2 Frost Protection Operation

During the ‘OFF’ periods, the heater will operate when the temperature falls below the frostthermostat setting.
