Unit Options RT -SVX20A-E4 44 Hot wat er coil (Down flo w units only) In order to prevent water to freez e up in the coil during unoccupied period or shutdown limited period, a thermostat opens when there is a risk of freeze-up. The services of a water treatment specialist are recommended if water used can cause scaling deposits or erosion.
Unit Options 45 RT -SVX20A-E4 Electr ic Heater Electric heaters are fitted on the fan disc harge. Heaters have two heating stages and provided with two types of overheat thermostats: • Automatic reset thermostats whic h stop the electric heater when the air temperature rises to 7 6°C.
Unit Options RT -SVX20A-E4 46 0 - 25% fr esh air hood The 0-25% fresh air hood allows to introduce fresh air into the unit. This is a manual device fitted on the bac k of the unit, siz ed for a maximum of 25% of the nominal rooftop air flow . This option includes for the hood itself, a wire mesh and a slidable damper .
Unit Options 47 RT -SVX20A-E4 Bar ometr ic r elief The barometric relief allows to minimize o verpressure in the building caused by the introduction of fresh air . This option is typically installed when fresh air intake is below 25% of the nominal air flow and when the return air pressure drop is below 25P a.
Oper ation RT -SVX20A-E4 48 Operation with a conv entional thermostat The ReliaT el module has conventional thermostat connections as well as Zone Sensor Module connections. When a conventional thermostat is controlling the unit, operation differs as follows: • Supply Air T empering feature is not available.
Oper ation 49 RT -SVX20A-E4 Logic is also provided to cause appropriate unit functions when inappropriate thermostat signals are provided. Simultaneous calls for heating and cooling will be ignored, and the fan will be turned on with a call for heating or cooling even if the fan request is not detected.
Oper ation RT -SVX20A-E4 50 Unoccupied mode If the thermostat being used is programmable, it will have its own strategy for unoccupied mode and will control the unit directly .
Oper ation 51 RT -SVX20A-E4 T o c hec k the damper is functioning correctly , the ECA is equipped with an indicator light in the middle of the board. This light operates as in T able 42. T able 47 - ECA board LED While setting the minimum position the damper may move tow ards the new setting in several small steps.
Oper ation RT -SVX20A-E4 52 T est pr ocedur es Operating c hecklist bef or e start-up • Unit is level, with sufficient clearance all round • Duct network is correctly siz ed according to the unit .
Oper ation 53 RT -SVX20A-E4 T est modes There are 2 methods in whic h the "T est" mode can be cycled with the test button: 1 . Step T est Mode This method initiates the different components of the unit, one at a time, by temporarily shorting across the two test terminals for two to three seconds.

Oper ation RT -SVX20A-E4 56 ReliaT el™ is a microelectronic control feature, whic h provides operating functions that are significantly different from conventional electro-mec hanical units. The master module is the ReliaT el™ Refrigeration Module (R TRM).
Oper ation 57 RT -SVX20A-E4 Low Ambient Operation During low ambient operation, outside air temperature below 13ºC, the R TRM will cycle the compressor and outdoor fan motor "Off" for approximately three minutes af ter every 1 0 minutes of accumulated compressor run time.
Oper ation RT -SVX20A-E4 58 Economizer Set-Up Adjusting the minimum position potentiometer located on the unit economizer Actuator (ECA) sets the required amount of ventilation air . T wo of the three methods for determining the suitability of the outside air can be selected utilizing the enthalpy potentiometer on the ECA, as described below: 1 .
Oper ation 59 RT -SVX20A-E4 Refer to the ignition control module diagnostics section for the LED diagnostic definitions. When the fan selection switc h is set to the "Auto" position, the R TRM energizes the supply fan relay (F) coil approximately 30 second af ter initiating the heating cycle to start the supply fan motor (IDM).
Maint enance RT -SVX20A-E4 60 T o keep the unit operating safely and efficiently , the manufacturer recommends that a qualified service tec hnician c hec k the entire system at least once eac h year , or more frequently if conditions war rant it.
