Health and Safety
This 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.
1.0 HOW THE CALOREX ‘SERIES 3 VARIHEAT’ SYSTEM WORKS.
The Calorex ‘SERIES 3 VARIHEAT’ range consists of 4 models: 600/900/1200/1500.
The model number increases in relation to the recirculated air flow from model 600 at 2000 m³/h to model
1500 at 4300 m³/h.
All models are fitted with either one or two “console fixing service panels” These allow for the console to be fixed to
the Variheat 3. These service panels can be fitted on any face of the machine.
When optional fresh air box is fitted, all models have the facility to exhaust a percentage of the recirculating
air and introduce a slightly lesser amount of fresh air (slight differential creates a negative pressure on
pool hall to localise pool environment and protect the building fabric).
An optional “negative pressure box” is also available. This exhausts a percentage of the circulationg air without
introducing fresh air to the pool hall.
All AW models are fitted with a fully controlled low pressure hot water air heating battery and a pool water heat
exchanger.
Provision is made for an external heat source to be initiated by the ‘SERIES 3 VARIHEAT’ controller.
All AW models have air and water heat exchangers recovering energy from the refrigerated dehumidification
process. These are also fully controlled with priority given to water.
Optional, factory fitted frost protection kits are available, these kit protect the LPHW from freezing by closing the
dampers to min when the ambient temperature is below 6ºC. The first kit controls the machine dampers. A second
kit controls the machine dampers and also a remote damper fitted by the customer in the installation ductwork.

THE CALOREX ‘SERIES 3 VARIHEAT’ RANGE.
FEATURES :All versions have removable driptrays for easy cleaning.
Control panel can be mounted remotely up to a maximum of 20 metre cable length.
Models fitted with a fresh air box or a negative pressure box have motor driven louvres on the exhaust and fresh air
dampers.
Optional electrical resistance air heater boxes ranging from 6kW to 18kW.
The power to each model in the range is fed in via din rail mounted terminal blocks located in the electric
box of the unit.
CONTROL PANEL. (All Models) Note AA Models do not have a water temperature controller, and do not
include a time clock unless fitted with LPHW.
The panel has the following features,
1. Relative Humidity Controller, with red light to indicate dehumidification demand.
2. Air Temperature Controller, with red light to indicate air heating demand.
3. Water Temperature Controller, with red light to indicator water heating demand.
4. Fresh Air Switch, with MAX, AUTO and MIN positions (for use with fresh air module or negative pressure box).
5. Economy Switch to select between water heating only or full function on AW versions.
6. On/Off Switch. NOTE with the switch in the OFF position the machine is still live and mains lamp and
clock are energised.
7. Air/Water switch, can be set to give priority to either water heating or air heating.
8. Time clock to control “occupied/unoccupied” timings with battery ‘back up’ and manual override.

1.1 OPERATION
When the SERIES 3 VARIHEAT is connected to the mains supply via an isolator and the isolator is energised,
the MAINS light on the side of the electric box will illuminate indicating mains ON and time clock will start to run.
The time clock has a battery reserve fitted which when charged will run for 100 hours so that isolating the machine
for short periods will not affect the time clock settings.
The SERIES 3 VARIHEAT unit is switched on to normal operation by an ON (I)/OFF (O) switch on the control
panel. When switched on the red indicator light will illuminate and digital controllers will light up.
Note digital water controller will be the only controller to light up when in economy mode.
Providing that the controls are set to the correct parameters; nominally 60% RH, 28ºC air temperature,
26ºC water temperature and fresh air switch set to AUTO, then the machine will operate automatically.
The ‘unoccupied’ temperature is set on the digital air controller and will be switched at the time set on the time
clock.
As the unit operates, the indicator lights will show the state of the control conditions, ie dehumidification,
heat to air and heat to water.
Other indicator lights are :Yellow for Fault (high or low refrigerant trip or soft start fault if fitted).
Yellow for Defrost
Green to indicate automatic operation.
See section 3.0 for control panel symbols.
PARAMETER CONTROLLERS
Each parameter, Relative Humidity, Water Temperature and Air Temperature is sensed within the machine
and the signal is taken to the relevant digital controller.
RH & Water Temperature controllers have two switching channels, also the Air Temperature controller for AA units
without room heating:
OUT1 which is set from the front panel, OUT2 which is factory pre-set.
The Air Temperature digital controller for units with room heating has three switching channels, one of which is for
setting OCCUPIED/UNOCCUPIED air temperature.
Each channel has a switching differential which is also factory pre-set. None of the factory settings should be
tampered with.
When the re-settable channel is adjusted all other settings and differentials automatically follow at the correct
relationship.
Nominal set point values & diffs RH%

diff 3%
diff 0.5 ºC
diff 0.2 ºC
Please note: on AA machines with no fresh air box or RCU, in occupied mode dehumidification stops once the Air
temperature is 2.5ºC above set point.
TIME CLOCK
The time clock setting determines the OCCUPIED/UNOCCUPIED periods and is set to match the operators
requirements regarding opening and closing times for the pool and possible times where the pool is covered.
The two settings are OCCUPIED or day time, and UNOCCUPIED or night time (covered).
The most obvious action of this change is to lower the pool hall air temperature to a determined level to
conserve air heating energy. This lowering of temperature is allowable because of the quiescent, and ideally
covered, condition of the pool.

2.1 PLUMBING
POOL WATER
The Calorex ‘SERIES 3 VARIHEAT’ should be connected as shown in section 3.0.
If an existing heater is being retained then the ‘VARIHEAT’ should be connected between the filter and the
existing heater.
Pool water connections on the machine are 1” BSPM stubs.
The unit is supplied with 2 off each of the following PVC fittings - 1”BSPFx 1”M
1”F x 1½”M
1½” x 50mm F
Suitable breakable couplings, isolation, and drain down valves should be installed in the pool water inlet/outlet
pipes local to ‘VARIHEAT’ unit.
The heat exchanger in the ‘VARIHEAT’ unit will, on small pools, take the full flow rate of the recirculation
system. On larger pools a bypass or separate auxiliary pump may be necessary. This method can also be
used to reduce energy consumption, by the installation of a two speed or auxiliary pump by-passing the main
pump/filter to satisfy pool water heating and dehumidification without the need for the main pump to be
running.
When the pipework installation is complete the circulating pump should be switched on and the system
checked for leaks. Also check the filter gauge to see that there is not excessive back pressure.
CONDENSATE DRAIN
The condensate driptray in the ‘VARIHEAT’ unit collects the water removed by the dehumidification process,
It is therefore necessary to ensure that the’VARIHEAT’ unit is placed on a level plinth so that the condensate
can run away and not overflow the edges of the driptray inside the machine.
All ‘SERIES 3 VARIHEATS’ have a 3/4” BSPM threaded condensate drain connection. The drain pipe should
run away with adequate fall to waste ie 1/2” per foot min. and must incorporate a ‘U’ trap & tun dish.
BOILER PLUMBING
The boiler connections on the machine are :3/4”BSPM on AW600/900
1” BSPM on AW1200/1500
for connecting the boiler water flow and return.
Suitable breakable couplings, isolation, and drain down valves should be installed in the boiler water
flow and return pipes local to the ‘VARIHEAT’ unit.
Water and air LPHW circuits internal to Calorex Heat Pump should be bled for air pockets. (Bleed valves fitted to
unit).
Refer to the boiler manufacturers instructions before designing the pipework system.
IMPORTANT GENERAL CONDITIONS
1. Do not route water pipes across service access panels or air inlet/outlets.
2. The water circuits to and from the ‘VARIHEAT’ unit should be capable of maintaining the specified
water flow limits required by the machine.
3. All pipework must be adequately supported with allowance for expansion and contraction especially with
regard to the plastic pipework.
4. It is recommended that when installing water systems the last connections to be made should be
adjacent to the ‘VARIHEAT’ unit to avoid undue stresses on the unit connections.
5. All pool purifying devices and chemical injection systems must be fitted down stream of the ‘VARIHEAT’
unit with a non-return valve to prevent concentrated chemicals back feeding into the heat exchangers.
6. The practice of dosing chemicals direct into skimmer basket must not be allowed as this would result
in concentrated corrosive liquids passing over vulnerable metal components.
7. Water quality must be maintained not only relating to solids, etc but for pH between 7.4 - 7.8, and if pool
water is saline at a maximum concentration of 8mg/litre.
8. See Warranty Exclusions section 6.0 for total list of water quality limits.
Page 10
SD437360 ISSUE 33
2.2 DETERMINING WATER FLOW
Flow Meter Method (see pool water schematics)
Ensure isolation valves ‘A’ and ‘B’ and bypass valve ‘C’ are fully open. Slowly close down bypass valve ‘C’
until correct flow rate is shown on the flow meter (see section 4.0).
Remove handle and lock off valve ‘C’.
Differential Pressure Method
By simply installing two filter pressure indicating gauges, one on the inlet and one on the outlet of the heat
pump, and a locking type gate bypass valve in the bypass line, the flow rate through the heat pump can be
accurately determined by the difference in the readings of the gauges. This pressure drop is proportional
to flow.
Flow rate should be set at the maximum differential with a clean filter fitted, this differential pressure will
drop as the filter becomes dirty. Provided the filter is cleaned before the minimum differential is reached
then no problems should be encountered (standard system only)
Setting up the differential
When the installation is complete, the procedure for setting the flow rate through the heat pump using two gauges
is as follows :1. With the heat pump switched off, ensure isolation valves ‘A’, ‘B’ and bypass valve ‘C’ are fully open.
2. Switch on water circulating pump.
3. Note the water system pressure on both gauges - they should read the same, but because of manufacturing
tolerance they may read different.
For example :- with a water system pressure of 5mhd the gauge on the inlet may read 5 and the outlet gauge 5.5
therefore there is a static error difference of 0.5mhd.
4. Gradually close the bypass valve ‘C’ until there is a difference in pressure between the two gauges that is equal
to the required pressure drop (see section 4.0) observing any static error on the gauges before beginning this
process.
5. Lock the bypass valve, or render it tamper proof when correct setting is achieved.
6. See section 4.0 for correct pool water pressure drop.

2.4 ELECTROLYTIC CORROSION IN SWIMMING POOLS
Electrolytic corrosion will occur when dissimilar metals that are in contact with each other create a potential
difference between themselves. Sometimes separated by a conductive substance known as an electrolyte, the
dissimilar metals will create a small voltage (potential difference) that allows the ions of one material to pass to the
other. Just like a battery, ions will pass from the most positive material to the more negative material.
Anything more than 0.3 volts can cause the most positive material to degrade.
A swimming pool with its associated equipment can create this effect. The pool water being an ideal electrolyte
and components of the filtration circuit, heating system, steps, lights etc providing the dissimilar metals needed to
complete the circuit.
Whilst these small voltages are rarely a safety threat, they can create premature failure through corrosion. Not
dissimilar to corrosion through oxidation, electrolytic corrosion can cause complete failure of a metallic material in
a very short period of time.
In order to prevent this type of corrosion all metallic components in contact with swimming pool water should be
bonded together using 10mm² bonding cable. This includes non-electrical items such as metal filters, pump
strainer boxes, heat exchangers, steps and handrails. It is highly recommended that bonding be retrofitted to
existing pools, which may not be protected by this system.
Page 14
SD437360 ISSUE 33
2.5 ELECTRICAL INSTALLATION
ELECTRICAL SAFETY
It is important to ensure that all aspects of the installation comply with the latest I.E.E. Regulations.
It is also important to ensure that any remote devices which terminate within the pool hall are of the type and
voltage as specified in the latest I.E.E. Regulations.
The machine should be installed in accordance with EMC2004/108/EC.
PROTECTED SUPPLY
Whilst not mandatory, Calorex recommend that an R.C.C.B. is always fitted or that the supply is to local
electricity authority recommendations, and that all ducting is bonded in accordance with these regulations.
The supply to the machine should incorporate fuses or motor rated circuit breakers (type GU, FAZC) to
specified rating (see data sheet) H.R.C. fuses are recommended. An isolator must be fitted within clear view
of the machine and not more than 2 metres away. The isolator must have a minimum of 3mm air gap when
in the off position.
INCONSISTENT ELECTRICAL SUPPLY.
The following limits of operation must not be exceeded if Calorex machines are to be guaranteed either in
performance or warranty terms :Voltage single phase 207V min, 253V max
Voltage three phase 360V min, 440V max
Frequency 47.5Hz min, 52.5Hz max.
N.B The voltage must be measured at the heat pump mains terminals with all the fans/compressors
running at the rated condition.
Please note that AW1200/1500 three phase machines are fitted with a phase rotation relay and will not run if the
phases are connected incorrectly or if the voltage is 15% less than 400V (340V) for a three phase 50Hz machine
CORRECT CABLE SIZING
The cable supplying electricity to a machine with a given load must increase in cross sectional area (CSA)
as the length increases in order that the voltage drop within the cable does not exceed recommended limits.
Cable sizing should be calculated by an approved electrician with due consideration to I.E.E. and local
codes of practice.
If resistance heaters are fitted an extra power supply will be required to the terminal blocks inside the
heater box, see data sheet for supply amps and fuse size.

2.5.2 NOTES ON TERMINAL BLOCK CONNECTIONS
NOTE 1 - Remote occupied/unoccupied
These contacts (from terminals 10 & 11) are to enable the air temperature set back facility to be remotely overridden. Please note that in unoccupied mode on AW machines, water heating does not take place unless there is a demand for dehumidification. There is a 12 Vac output from these terminals and closing a remote switch will enable the unit to regain the normal operating air temperature for when the pool is in use. This can be done via a voltage free pool cover switch or some other form of voltage free switch. If this facility is used then the time clock (if fitted) on the control panel of the unit should be set to the ‘unoccupied’ (o) position. (See note on time clock and switch settings, section 3.2.1). If these terminals are fitted on versions without time clocks then they MUST BE LINKED. NOTE 2 - Pool pump start -AW only (see also section 3.2.2)
These are voltage free contacts (from terminals 8 & 9) rated at 3(1) Amp at 230 Volts. If the pool water pump is to be run via an external time clock then these connections should go across the switching contacts of the external time clock to ensure that, if dehumidification demand occurs the pool water pump will start. The pool water pump will exceed the one amp inductive rated current of these contacts therefore a contactor or relay should be used to switch the load of the pump.The switching action of the external time clock should energise the contactor/relay coil. If the pool water pump is to be run continuously then these contacts can be ignored. NOTE 3 - Boiler demand -AA+LPHW & AW machines only
These are voltage free contacts (from terminals 6 & 7) rated at 3(1) Amp at 230 Volts. If the low pressure hot water supply to the unit is to be governed by the Calorex unit then these contacts should be utilised to bring water to the unit via the boiler, motorised valve, boiler pump etc. Remember the maximum inductive load is one amp. This is dependant on how the low pressure hot water supply to the unit has been designed. If the supply of low pressure hot water to the unit is not dependant on a signal from the unit then these contacts can be ignored. NOTE 4 – SEPARATE SUPPLY FOR RESISTANCE HEATER BOX
If resistance heaters are fitted then an extra power supply will be required to the terminal blocks inside the heater box. See section 4.0 for supply amps & fuse size. CONTROL PANEL 25 WAY CABLE CONNECTION
Data signal between control panel and electric box is via a 25 way cable with ‘D’ connection (plug & socket) both ends. Page 17

3.1 COMMISSIONING CHECKLIST
a. Is the building finished in accordance with the original plans and specification.
b. Is the plenum chamber and all ductwork insulated, special attention should be made to the insulation of the
exhaust air ducting and fresh air inlet ducting to prevent condensation problems.
c. Are there any significant draughts in the pool hall or plant room (plenum installation) through poorly fitting doors,
windows, pipe ducts, etc. This will let in unwanted ambient air raising the heating duty required.
d. Is fresh air suction and exhaust air discharge ducting (if fitted) perfectly sealed from plant room.
NOTE: (c) and (d) above should be checked by measuring plant room and pool hall air temperatures.If the plant
room is acting as a plenum chamber both temperatures should correspond. If the plant room temperature is
lower then ambient air is leaking in, this leak should be located and rectified.
e. Are the fresh air inlet and exhaust air outlets free from obstructions ie, undersize grilles, objects in the path of
exhaust air deflecting it back to the fresh air inlet, etc.
f. Is ‘occupied / unoccupied’ set correctly, (set with air thermostat) see section 3.2.3.
g. Is the time clock set correctly.
h. Is start up (‘fresh air flow’ switch to ‘min’) feature required and if so is customer aware of when to switch
machine back to ‘Auto’.
i. Has the Calorex Heat Pump been bled for air pockets. (Bleed valves fitted to unit as standard).
j. Any sign of abnormal operation such as water dripping should be reported immediately to an installer or Calorex.
k. Is airflow sufficient through machine? Remove fan damper plates and check fan amps.
l. Check belts and filters are fitted correctly.
3.2.1 TIME CLOCK SETTINGS
The time clock is a quartz 24 hour clock with 100 hours battery reserve used to control the automatic
operation or the SERIES 3 VARIHEAT unit per 24 hour time cycles.
SETTING ACTUAL TIME
Turn the large clock hand clockwise until the correct time of day is set, ensuring that the correct half of the
day is chosen (24 hour clock).

SETTING FOR AUTOMATIC OCCUPIED/UNOCCUPIED OPERATION WITH TIME CLOCK
To set for automatic time clock control of occupied/unoccupied, slide the lever to ‘A’. Each yellow segment
represents a 15 minute time period. Extend outward the segment s for a period of time that the pool is occupied
(i.e. used or uncovered) per day.
If the unoccupied period is more than 20 hours per day, extend one segment at 9:00 or other suitable time that
does not coincide with the main occupied period*.
Page 27
SD437360 ISSUE 33
SETTING FOR AUTOMATIC OCCUPIED/UNOCCUPIED OPERATION WITH REMOTE INTERFACE
To set for remote control of occupied/unoccupied, slide lever to ‘O’. See section 2.4, Note 1 for more information on
remote interface. If the unoccupied period is more than 20 hours per day, extend one segment at 9:00 or other
suitable time that does not coincide with the main occupied period.* Ensure all other segments are pushed inwards and slide lever to ‘A’.
SETTING FOR MANUAL OCCUPIED/UNOCCUPIED OPERATION
To set for manual occupied period (or override automatic unoccupied period) slide the lever to ‘I’ for ‘occupied’. If
the unoccupied period is more than 20 hour per day, to set for a manual unoccupied period slide the lever to ‘O’ for
‘unoccupied’; extend outwards one segmentat 9:00 or other suitable time that does not coincide with the main
occupied period* and ensure all other segments are pushed inwards.
*In unoccupied mode, the pool water is not heated unless a demand for dehumidification occurs during this period.
If the unoccupied is more than 20 hours per day, it is recommended to allow a brief occupied period to allow the
water temperature to be sampled and maintained if necessary.

CONTROLLER ON AA MACHINE WITHOUT AIR HEATING
To Program the Set Point. Press down P, SP1 and Set Point value will be displayed alternately. Press the or key to change the value of SP1. Once the desired value is displayed press P to memorise the value. The display will revert to the present reading. NOTE: If anything else shows on the display leave alone for 1 minute until the display returns to normal. AIR TEMPERATURE DIGITAL CONTROLLER AW AND AA MACHINES WITH AIR HEATING
The digital controller for controlling air temperature can be changed as follows:- To program the set point, press P button once and release it. SP1 (set point) and set point value e.g. 28 will be displayed alternately. Press P again AL1 (-4.5) will show. This is the difference between the set point and AL1 plus a constant 0.5 e.g. 28 - 4.5 + 0.5 = 24ºC (unoccupied) SP1 and AL1 can be changed in the same way as described for humidity and air. NOTE: AL1 can only be set -1 to -10 below SP1 value. If the reading on the digital controller is not the same as the actual pool hall temperature, water temperature or relative humidity it may be necessary to program an offset into the digital controller.

7.0 LOGIC CONTROL CIRCUITS
NOTES
1) SIGNAL TO START BOILER PUMP IS VIA TERMINAL BLOCKS 6 & 7 (VOLTAGE FREE SWITCH).
SIGNAL TO START POOL FILTER PUMP IS VIA TERMINAL 8 & 9 (VOLTAGE FREE SWITCH).
MACHINE WILL BRING ON POOL FILTER PUMP (IF IT IS NOT ALREADY RUNNING) WHENEVER THE
COMPRESSOR RUNS OR WATER HEATING IS REQUIRED (SEE NOTE 10).
2) SET POINT OF THERMOSTATS IS REFERRED TO AS THE SWITCHING POINT FOR SIMPLICITY WHEN IN FACT
THE RELAY OPERATES AT SET POINT PLUS OR MINUS THE HYSTERESIS. (SEE GRAPHS BELOW).
3) WHEN MACHINE IS ON DEFROST THE FAN STOPS (UNLESS FAN IS ON DUE TO RESISTIVE HEATERS BEING
WARM) BUT ALL OTHER FUNCTIONS OPERATE AS NORMAL.
4) IF FRESH AIR SWITCH IS SET TO 'MIN’ THE DAMPERS (AIR BOX) ARE FORCED TO
CLOSE AND WILL NOT BE UNDER MACHINE ‘AUTO' CONTROL.
5) AIR STAT NEON (OUT2) WILL SHOW DEMAND ON UNOCCUPIED SETTING BUT NOTHING WILL HAPPEN
BECAUSE CONTROL IS BY OUT1 STAGE OF AIR STAT (UNOCCUPIED).
6) TIME CLOCK MUST BE OVERRIDDEN AND UNOCCUPIED (PIPS IN) SELECTED IN
ORDER THAT THE REMOTE 12V SWITCHING FEATURE CAN OPERATE.
MACHINE TERMINALS 11 & 12 ARE 12VAC
OPEN CIRCUIT = UNOCCUPIED
CLOSED CIRCUIT = OCCUPIED
7) AUTO PANEL NEON ONLY WORKS WITH AIR BOX FITTED.
8) DEHUMIDIFICATION/AIR HEATING DOES NOT HAPPEN WHEN IN ECONOMY MODE.
9) IF REMOTE ON/OFF LINK (TERMINAL 12 & 13) IS REMOVED MACHINE WILL NOT START.
10) IN ECONOMY MODE WHEN WATER HEATING IS REQUIRED THE POOL PUMP RUNS AND LPHW VALVE
OPENS ONCE THE 60 min TIME DELAY HAS TIMED OUT).
IN UNOCCUPIED MODE (AND NOT ECONOMY). POOL PUMP AND LPHW WILL ONLY OPERATE ONCE THE TIME
CLOCK HAS PIPPED (OCCUPIED) OR DEHUMIDIFICATION STARTS, THEN KEEPS RUNNING UNTIL THE WATER
TEMPERATURE IS SATISFIED.
11) RESISTANCE HEATER CAN SOMETIMES REPLACE AIR LPHW. (BOILER PUMP WILL NOT START WITH AIR
RESISTANCE HEATING).
12) RCU IS ENERGISED ON AS3 IN OCCUPIED MODE ONLY. RCU FAN WILL START WITH COMPRESSOR, AND
CHANGE RCU SOLENOID VALVE FROM A TO B (A CLOSES - B OPENS) UNLESS MACHINE IS IN DEFROST MODE
WHICH WILL THEN KEEP VALVE A ENERGISED.
13) TEST SHEETS (CERTIFICATE OF PERFORMANCE) PART NoS A444050 to 57.
14) WHEN FAN IS SET TO CYCLE MODE, FAN ONLY RUNS WHEN MACHINE HAS DEHUMIDIFICATION OR AIR
HEATING DEMANDS. CYCLE MODE IS TERMINALS 33 & 34 LINKED (MADE), LINK TERMS 32 & 34 IN
CONTINUOUS MODE.

7.1 RELAY FUNCTIONS
R1 Energised on power on switch being made on AA and AA+LPHW /resistance heating.
Energised on power on switch being made and economy switch in the full operation mode on the AW.
When not energised and the machine is switched on allows the pool pump & water LPHW to operate
in economy mode once 60 min timer on AW machine (if fitted) has timed out, when water temperature
is below stage 1.
R2 Energised when stage 1 (unoccupied) or stage 2 in occupied mode. Air heating is needed bring on
the LPHW air valve or resistance heater (used on AA machine to bring on the fan if air is below
stage 1. R4 has to be made in occupied mode). It will also bring on the fan on all machines if fan is
not already running.
R3 Energised when dehumidification is needed as long as LP and HP pressure switches are not in
fault mode.
R4 Energised when time clock is in occupied mode on AA+LPHW / resistance heating and AW
machine. On AA with air box or RCU energised once the power switch is made.
R5 Energised on humidity still rising above stage 2, which in turn will open the dampers (only if air box
is fitted and R4 is energised).
R6 Energised when damper switch on control panel is switched from auto mode (only if air box is fitted).
R7 Energised to switch the air box to max (if air box is fitted).
R8 Energised when water temperature is above stage 2 it energise the reversing valve to send dehumidification
heat to air (AW machine only).
R9 Energised if LPHW water heating is required to start the pool pump only in the occupied mode
and economy mode or if at any time dehumidification is happening (AW machine only).
R10 Energised by relay 9 to bring on water LPHW valve. Only if water temperature is below stage 1
in occupied mode only. (AW machine only).
R11 Used on AA / AA+LPHW / resistance heating machine without options to stop dehumidification once
air temperature is above stage 2 on AA machine, above stage 3 on AA+LPHW / resistance heating.
R12 Used only if RCU unit is fitted energised if air temperature is above stage 2 on an AA machine with
out time clock or stage 3 on all other machines.
R13 Used only on AW machine to start LPHW water heating and pool pump if water temperature is
below stage 1 in the occupied mode only.
R14 Provides volt free contacts for remote ‘control power’ indication.
RE 1 Energised by R2 to bring on the fan when the fan is wired to cycle mode when air temperature is low.
RE 2 Energised in defrost mode to bring on defrost lamp and if RCU is fitted to change back to
valve A if RCU is calling for, valve B when machine is in defrost mode.
RE 3 Energised once R1 is made unless the soft start has a fault or soft start link is broken.
Which would cause RE 3 to drop out bring on the fault lamp.
RE 4 Provides volt free contacts for fan running.

Programming the offset
If the reading on the digital controller is not the same as the actual pool hall air temperature, water temperature or
relative humidity, it may be necessary to program the offset.
Press and hold the P key for approximately 2 seconds. You will then enter the programme control group menu.
Press the up key to reach ConF, then press P again and enter the password -281 by holding the down key. If you
pass -281 use the up key to go back, then press P again. This takes you into the programmable group menu.
Press the up or down key to get to groupInP and then press P again. Press the up key until OFSt is displayed.
This parameter can be adjusted by pressing the P key and then the up and down key until the Tecnologic stat
reading and the actual reading are the same.
Example: If the Pool water is 26.0ºC and the digital controller reads 25.5ºC the offset to be entered is +0.5.
When the correct offset has been inserted, leave the stat alone for 20 seconds and the display will return to
normal. Great care should be taken to leave all other parameters at their factory settings.
